66 Core Journals in Library and Information Science: Developing a Methodology for Ranking LIS Journals Judith M. Nixon Judith M.

Nixon, Attribution-NonCommercial (http://creativecommons. org/licenses/by-nc/3.0/) CC BY-NC In the library science field, there is no professionally accepted tiered list of journals in the United States to guide librarians, as there is in other academic disciplines. This situation creates a challenge for both new and experienced librarians who wish to make a serious contribution to librarianship by publishing articles. This article outlines a methodology used at the Libraries of Purdue University, which could be adapted by other university libraries, to create a tiered list of journals tailored to the institution. The article begins with a literature review that identifies a short list of top-level journals. This is followed by the methodology that uses expert opinion surveys, acceptance and circulation rates, impact factors, h-indexes, and journals with local faculty articles. Tables with the journals ranked into three tiers are included. Background and Reasons for Compiling a Tiered List of LIS Journals In library and information science (LIS) there is no professionally accepted tiered or ranked list of journals in the United States. This creates a dilemma for librarian-authors who wish to expand the literature in librarianship, write about successful programs, or report on research findings. Every librarian- author faces the question of where to submit the manuscript. The choice can have significant consequences on how many librarians will read it, how often the article will be cited, and the impact or influence it will have. This dilemma is especially critical for those in faculty status positions seeking promotion and tenure, as they are advised to have a steady flow of refereed articles in the major journals in the field.1 The advice ap- plies to all librarian-authors at all stages of the career. Submitting to peer-reviewed journals is a well-recognized step; how- ever, with over 250 refereed LIS journals, identifying one is problematic. A tiered list of journals would provide guidance for both the faculty member preparing for promotion and the committees evaluating the portfolio. At Purdue University, as at most uni- versities, promotion and tenure decisions go through three committees. The first committee’s membership is all associate and full professors in the library; the second and third committees have some nonlibrarian full professor members. A tiered list of journals would provide guidance for the second and third review committees, wherein most members are unfamiliar with the journal literature of crl12-387 Core Journals in Library and Information Science 67 the library science field. As a matter of fact, the needs of the second and third promotion review committees provided the initial impetus at Purdue Libraries to compile the list. A list of top-tiered journals would en- courage librarians to match articles to the journals level. Beginning authors might avoid rejection from a top-tiered journal by submitting to a middle-level journals, as these journals are less competitive and often do not require research articles. Editors of these journals frequently have the time to work more closely with authors to develop a publishable article. Experienced librarian-authors writing full-fledged research articles could use the list to identify top-level journals and different journals than where they have published in the past. As the writer be- comes familiar with the style and scope of specific journals and is encouraged by past successes with submissions, it is normal and natural to favor these. How- ever, in some cases these journals tend to be mid-level journals. A ranked or tiered list would encourage librarians to submit to higher-ranked journals. In Australia the professional associa- tion has developed a tiered list.2 However, in the United States, no association has been willing to take on the responsibility of developing a methodology or compil- ing such a list. This motivated the library faculty at Purdue University Libraries to compile a tiered list of journals to be used internally as a guide for our faculty mem- bers and promotion review committees. This effort led to the idea of developing criteria to identify a list of tiered journals and to update it annually. The purpose of this article is to share our methodology and the resulting tiered list of journals with other librarians, especially those with faculty status. Probably no two university committees would agree on the list, so the final list given here is not as important as the methodology, which could be adapted for use elsewhere. A preliminary tiered list of journals with 67 titles in tier one, including a few that are not peer-reviewed, and 15 titles in tier two was accepted by the Purdue University Library faculty and referred to the full professor subcommittee of the Purdue Libraries Primary Promotion and Tenure Committee. Sixty-seven titles in tier one seemed like an overwhelming number, especially since it included some non–peer-reviewed titles. There were serious questions about whether such a long list would be helpful to untenured faculty members. As one of the full pro- fessors, I accepted the challenge to see if some method could be developed to divide the list. Literature Review In the literature on this topic, eight ar- ticles stand out: an expert opinion study by David Kohl and Charles Davis,3 two replications,4 and five journal citation studies. Three citations studies were done in the 1990s: one by Mary Kim,5 a second by John M. Budd, 6 and third by Belen Altuna Esteibar and F.W. Lancaster.7 Two additional citation studies were published in 2007, bringing the research into the cur- rent decade: one by Kelly Blessinger and Michele Frasier8 and a second by Barbara Via and Deborah Schmidle.9 A review of the findings of these articles and a merged list of the top ten journals in each study produced a list of top-tier journals. In ad- dition, the literature review identified the methods used that served as guidance for the creation of the criteria. “Expert Opinion” or Perception Surveys The David Kohl and Charles Davis arti- cle,10 “Ratings of Journals by ARL Library Directors and Deans of Library and Infor- mation Science Schools,” has been heavily cited and replicated twice. This study asked the deans of American Library Association–accredited library schools (referred to as “deans” throughout the present article) and the directors of As- sociation of Research Libraries (referred to as “directors”) to rate 31 core journals on a scale of 1–5 (Likert scale). To do this study, Kohl and Davis had to provide a 68 College & Research Libraries January 2014 list of LIS journals. Their list constituted a revision of Jesse Shera’s “hard-core of library literature” published in his 1976 book Introduction to Library Science.11 Kohl and Davis found a hierarchy and agree- ment between the deans’ and directors’ rankings on two-thirds of the journals. When the top ten choices of both the directors and the deans were compared, six titles appeared on both lists. In alpha- betical order, they are College & Research Libraries, Information Technology and Libraries, Journal of the American Society for Information Science (title changed to Journal of the American Society for Infor- mation Science and Technology (JASIST)), Library Quarterly, Library Resources and Technical Services, and Library Trends. The directors added American Libraries, Journal of Academic Librarianship, Library Journal and RQ (title changed to Reference & User Services Quarterly). The deans included Drexel Library Quarterly (now ceased), Journal of Education for Librarianship, Library and Information Science Research, and Special Libraries.12 A list of the top twelve titles selected by the directors and deans constituted a working list of top-ranking journals. (In this list American Libraries was not included as it is not peer- reviewed, and Drexel Library Quarterly was removed as it ceased in 1986). These titles, listed in alphabetical order, were then compared with the top titles in the other major articles. Top Journals from the Kohl-Davis Study: 1. College & Research Libraries 2. Information Technology and Libraries 3. Journal of Academic Librarianship 4. Journal of Education for Librarian- ship 5. Journal of the American Society for Information Science (title changed to Journal of the American Society for Information Science and Technology (JASIST)) 6. Library and Information Science Research 7. Library Journal 8. Library Quarterly 9. Library Resources and Technical Services 10. Library Trends 11. RQ (title changed to Reference & User Services Quarterly) 12. Special Libraries Two replications followed the Kohl- Davis study during the following twenty years. In 1995, Virgil Blake13 replicated the 1985 study. When the top ten journals from the directors and the deans, 13 titles, were compared to the top ten choices in the 1985 study, 11 titles overlapped. The two new titles were The Chronicle of Higher Education and Journal of Documentation. Since the Chronicle is not a LIS journal, Blake only added one new title for consid- eration to the top journal list. (See table 1 for the rank of each title in the Blake study and all other studies.) In 2005, the Kohl- Davis study was replicated again, this time by Thomas Nisonger and Charles Davis. Combining the top ten choices of the deans and directors produced a list of 14 titles. Four new titles appeared; however, two of the new titles are not truly journals and so were omitted from consideration. The two Nisonger and Davis added were Information Processing and Management and Library Collection, Ac- quisition, & Technical Services. (See table 1.) Although there were differences in the ranks assigned to the journals by each group and each group had some unique titles high on their list, a list of top jour- nals was evident. Titles that appeared on all three lists include College & Research Libraries, Information Technology and Li- braries, Journal of Academic Librarianship, Journal of the American Society for Informa- tion Science (title changed to Journal of the American Society for Information Science and Technology (JASIST)), Library & Information Science Research, Library Quarterly, Library Resources and Technical Services, Library Trends, and RQ (title changed to Reference & User Services Quarterly). Titles that ap- peared on two of the lists include Journal of Documentation, Journal of Education for Library & Information Science, and Library Journal.

Core Journals in Library and Information Science 71 Kohl-Davis list by changing two titles: Special Libraries was omitted and Journal of Documentation was added. (See table 1 for ranks of the top ten titles in each study.) In sum, the top journals identified in the three expert opinion surveys, in alphabetical order, were: 1. College & Research Libraries 2. Information Technology and Libraries 3. Journal of Academic Librarianship 4. Journal of Documentation 5. Journal of Education for Library & Information Science 6. Journal of the American Society for Information Science (title changed to Journal of the American Society for Information Science and Technology (JASIST)) 7. Library & Information Science Re- search 8. Library Journal 9. Library Quarterly 10. Library Resources and Technical Services 11. Library Trends 12. RQ (title changed to Reference & User Services Quarterly) Citation Studies Since all the studies discussed above are expert opinion rankings and, therefore, subjective, the question arose as to wheth- er these ratings reflected the actual impor- tance of the journals or just “clusters of high and low prestige.”14 To investigate this question, Mary Kim15 did a citation analysis study in 1991 comparing more objective factors of citation-based mea- sures with the rankings from Kohl-Davis. She expanded the 31-title list to include all English language citing and cited LIS source journals in Journal Citation Reports® and also added major journals published by the American Library Association. The result was 52 journals. If a title was not included in Journal Citation Reports®, the citations were hand-tallied. She found that “both deans and directors assigned higher rankings to those journals receiv- ing more direct citations.”16 And that “the discipline citation measures identified a core of top journals that overlapped well with the core listings of the directors and deans for a similar time period.”17 Of the top ten titles identified in this study, nine were on our top twelve title list, and the only title not on this list was American Libraries, which had been identified in Kohl-Davis but is not peer-reviewed. Clearly, the titles that emerged from this citation study overlapped with the expert opinion studies. (See table 2 for titles and ranks of the citation studies.) Two important citation studies fol- lowed shortly after Kim’s study. In 1991 John M. Budd analyzed 328 articles in- dexed in the ERIC database with the major descriptor “Academic Libraries” between 1984–88.18 He identified 40 library– or information science–related journals and listed the most frequently cited journals. Comparing the top ten in his list with top 12 titles identified by the expert opinion studies, seven titles overlap. Two of the three new titles identified in his study are not peer-reviewed: College & Research Libraries News and American Libraries. His study added one peer-reviewed title not mentioned in the other citation analysis articles, Special Libraries. However, this title was identified in the expert opinion articles as a top journal and so was not a new title for consideration. In 1993, anoth- er citation study was done by Belen Altuna Esteibar and F.W. Lancaster. They ranked journals by the number of “mentions they received in 131 course readings lists” at the GSLIS at the University of Illinois Urbana- Champaign and “by the number of times cited in doctoral dissertations and in fac- ulty publications.”19 They then weighted the scores, giving more weight to faculty publications. The top ten journals in this weighted ranking overlapped closely with other citation studies and our list of top journals. A peer-reviewed title that did not appear before in the citation studies was Information Processing and Management. Another title that did not appear before was Illinois Libraries; however it is not a peer-reviewed title. (See table 2 for titles and ranks from the citation studies.) 72 College & Research Libraries January 2014 In 2007, two other major citation stud- ies were published. Barbara Via’s and Deborah Schmidle’s20 goal was to measure return-on-investment of LIS journals using citation analysis. To do this, they measured “the frequency with which individual library journals are cited in the bibliographies of a core group of Library and Information Science journals that, arguably, comprise the premier journals in the Library and Information Science field.”21 The core journals were chosen from the top titles in both the deans’ and directors’ list in the Nisonger-Davis study. Through this method they identified 19 journals that were cited 100 times or more. The top ten journals (those referenced 245+ times) overlapped closely with our top 12 journals identified in the expert opinion studies. This study added Infor- mation Processing and Management, which had also been identified by the deans in the 2005 Nisonger-Davis study, and Jour- nal of Information Science, which was not identified by any of the expert opinion studies, for consideration to the list of top journals. Also in 2007 Kelly Blessinger and Michele Frasier22 did an analysis of ten years of library literature, from 1994 to 2004. Their study revealed areas of concentration, frequently published sub- jects, and characteristics of the top-cited authors and resources. Journal Citation Reports® was used to determine the 28 journals of high repute for the study. However, like the Via-Schmidle article, this study also was useful in the quest for the top journals, as one of the results was a list of titles with over 100 citations at- tributed to them. The top ten titles in this study all had over 350 citations. Like the Via-Schmidle and the Esteibar-Lancaster articles, they also identified Information Processing and Management. (See table 2 for titles and ranks of the top ten journals in the citation studies.) Here is a merged list of the top jour- nals (those listed in four or more of the expert opinion or the citation studies) in alphabetical order: 1. College & Research Libraries 2. Information Processing and Man- agement 3. Information Technology and Libraries 4. Journal of Academic Librarianship 5. Journal of Documentation 6. Journal of the American Society for Information Science (title changed to Journal of the American Society for Information Science and Technology (JASIST)) 7. Library & Information Science Re- search 8. Library Journal 9. Library Quarterly 10. Library Resources and Technical Services 11. Library Trends 12. RQ (title changed to Reference & User Services Quarterly) The first result of the literature review of the citation studies was that the expert opinion studies are accurate and useful in identifying top journals. Second, it provided an additional title for the top- tier journals, Information Processing and Management, which was listed in three of the citation studies. Only the Journal of Education for Library & Information Sci- ence, which was on the list of top journals identified in the expert opinion surveys, was not included here. Third, this lit- erature review showed that the most frequent methods for compiling a list of top journals are to survey the experts and to use citation studies. In addition, an overall result of the literature search was recognition that there are journals in the field that are prestigious; a small number of journals are consistently listed on expert opinion surveys and rank high on citation studies. Relying on published studies has the innate problem that they are not current. New journals are started; older journals cease, change their focus, or do not retain their standards. The goal of this project was to develop a methodology that can be used annually to identify the most important journals in the LIS field. This list of important journals should be longer than the list of top journals identified in Core Journals in Library and Information Science 73 TA B L E 2 Jo ur na ls R an ke d as T op 1 0 T it le s in C it at io n St ud ie s D is cu ss ed N um be rs in c ol um ns 2 -6 a re th e ra nk fo r e ac h tit le fr om in e ac h st ud y.

The next step was to develop criteria for a tiered list. Developing Criteria for the Tiered List The goal of this research project was to develop a list of top-level journals divided into tiers. The list was not intended to be proscriptive; rather, it would serve as a guide to help faculty members and promo- tion review committees identify the influential LIS journals. Tier one should include the most influen- tial journals, which we anticipated would be very similar to the titles identified in the expert opinion and citation studies listed above. These would be journals that library faculty members, especially more experienced researchers, would be encouraged to consider when sub- mitting research articles. Tier two should include recognized, but less prestigious, journals. The tiered list could not be a comprehensive list of all acceptable journals for promo- tion, as librarians at Purdue are also encouraged to publish in journals outside the LIS field to reach a more appropriate audience. To develop the tiered list, a set of criteria was selected. The first crite- rion was peer review; both tier one and tier two would be peer-reviewed titles. There are a few journals, such as Library Trends and Library Journal, of high scholarly level that are not peer-reviewed. These journals, which invite authors to write on specified topics, are considered by our pro- motion committee as of the same value as peer-reviewed titles and so are included in the same category as peer-reviewed titles. In addition, as the literature review indicated, there are a few non–peer-reviewed titles that are highly recognized in the field and frequently cited.

Core Journals in Library and Information Science 75 tier was added to include the important non–peer-reviewed titles, such as College & Research Libraries News. After peer-reviewed status, the next criterion chosen was a high rank in a recent expert opinion survey. The Kohl- Davis and Nisonger-Davis articles stood out in the literature review. These articles were cited in nearly every reference list, and frequently the top journals in these studies have been used as the “core list” for other studies. The Purdue University Libraries Promotion & Tenure Commit- tee, in fact, was referencing the Nisonger- Davis list in promotion documents before the Faculty Affairs Committee compiled the tiered list. Since the Nisonger-Davis article is the second replication, it is anticipated that it will be updated again within the next five years. Therefore, it was identified as a major source for selection. Additional criteria included low accep- tance rate, high circulation rate, journals that Purdue University Libraries’ faculty members had published in more than two times in the last ten years, and two citation ranking sources: the Institute for Scientific Information’s (ISI) impact factor and the h-index calculated from Google Scholar data. The advantages and disadvantages of each of these criteria are discussed below. To summarize: Essential Criteria 1. peer-reviewed (or invited) titles in LIS field Variable criteria (a tally was given for each of these criteria) 2. expert opinion (top rating by Deans’ list in Nisonger-Davis 2005 study) 3. expert opinion (top rating by Directors’ list in Nisonger-Davis 2005 study) 4. acceptance rate below 50 percent 5. circulation above 5,000 6. journals that Purdue University Libraries’ faculty members have published in more than two times in the last ten years 7. journals with an ISI impact factor 8. journals with an h-index above 7, as calculated using Google Scholar data Other possible criteria discussed, but not added, were EigenfactorTM scores, jour- nals indexed in the major databases, highly rated titles in the Via-Schmidle citation study, and open access journals. The Eigen- factorTM scores were not included because they are only available for journals indexed in ISI’s Web of Science. Since all journals indexed by ISI already received one tally, this would give favor to those journals. Inclusion in the major indexing/abstracting tools has been used by libraries as a crite- rion for journal retention. However, nearly every journal on the peer-reviewed list of LIS journals is included in at least one of the indexing/abstracting tools in the field, so this criterion would not separate major from lower-level journals. A high rating in the Via-Schmidle study was not included because it is possible to gather more cur- rent citation data. Giving a tally to open access journals was seriously considered. However, research by Jingfeng Xia23 using the h-index indicates that open access jour- nals do not consistently score high. More research is needed on whether open access is a reliable criterion for quality. Gathering Data on LIS Journals The following steps were taken to build the spreadsheet with data matching the criteria. (See table 3 for titles and data.) Peer-reviewed LIS journals were identi- fied by using UlrichsWeb, which listed 506 journals that met their definition of actively published, refereed, academic/ scholarly journals published in English. These titles were imported into a spread- sheet for analysis. UlrichsWeb has a sepa- rate record for every format of a journal; merging identical titles reduced the total to 217 titles. During this import, the ISSN numbers were also gathered and used for merging other data; this avoided the problem of variations on titles between databases. An additional search was done in UlrichsWeb to identify the journals with a circulation of over 5,000. 76 College & Research Libraries January 2014 TA B L E 3 : T it le s in S tu dy in A lp ha be ti ca l O rd er T it le R ef er ee d D ea n' sa D ir ec to rs a A cc ep ta nc e R at eb C ir cu la ti on in 2 01 1 IS I Im pa ct F ac to r #

All journals that were rated as greater than 2.0 (ranked 1–40 of 71 ranked journals) by the directors received a tally as did all titles rated by the deans as greater than 2.0 (ranked 1–42 of 71 ranked journals). Since Nisonger-Davis’ table 1 has two lists, deans and directors, a journal could get two tallies. These ranks were manually added to the spreadsheet. The advantages of using the Nisonger-Davis’ expert opin- ion study are ease in compiling the data and its status as an authoritative article. The disadvantage is that it is not as cur- rent as preferred. All titles with an acceptance rate below 50 percent received one tally. This was approximately the average acceptance rate. Acceptance rate was selected partially because it provided a data point that was completely separate from the expert opinion or citation data and because a journal that receives two or more times the number of submis- sions it can publish is able to select the best. Some research has confirmed this relationship. Haensly, Hodges, and Dav- enport found lower acceptance rates to be associated with higher citation counts, impact factors, and expert opinions (or survey-based rankings) and concluded that it could be used as a reasonable proxy for journal quality.24 Acceptance rates were not readily available for all titles on the list, although Cabell’s Di- rectories of Publishing Opportunities, in the section on Educational Technology & Library Science, had acceptance rates for 266 titles, of which about 130 were library-related journals. The Cabell rates were retrieved in August of 2010 and merged into the database by matching titles. To supplement the Cabell data, the author e-mailed journal editors asking their acceptance rate, and the response rate was quite high. If a journal had an acceptance rate below 50 percent, either in Cabell’s or as reported by the editor, a tally was credited. Besides being dif- ficult to obtain, the main disadvantage to using the acceptance rate is that there is limited research on how valid it is as an indicator of quality, causing some editors to be reluctant to provide this statistic. However, other journal editors, often those with high acceptance rates, reported working closely with authors to improve otherwise unacceptable articles. Journals with a very high circulation rate, a rate of 5,000 or higher, were given one tally. Since every author’s goal is to reach as wide a population as possible, giving one tally to high circulation titles was logical. It also provided a criterion that was completely different from the other criteria. Circulation data were found in UlrichsWeb and gathered with the import of the peer-reviewed journals initially. The major advantages of using circulation rate as an indicator are that they are logical and readily available. The major disadvantage is that there is no re- search indicating a relationship between circulation and quality. The next criterion was to give each journal that had three or more articles published by Purdue Libraries faculty members during the last ten years a tally point. This provided the faculty with input into the process via their choice of publication venue. It is somewhat similar to the expert opinion criterion and is logi- cal in that new faculty members would consider publishing where their more experienced peers published. The list of Purdue University Libraries journals was compiled from the annual list of publica- tions in Purdue Libraries Annual Report,25 an in-house publication that is posted on the Purdue Libraries web page. Tallies were added manually to the spreadsheet. The advantages of this criterion are that it provides recognition of journals favored by the faculty and is easy to compile. Its disadvantage is that the ranking of journals in this study favors publications chosen by Purdue Libraries faculty for publication venue. Other libraries using these metrics will need to compile and adjust their data accordingly. Core Journals in Library and Information Science 83 All titles with an ISI impact factor re- ceived one tally. They were retrieved from Thomson Reuters’ Journal Citation Reports® for the 73 journals included in their “Infor- mation Science & Library Science” subject category in the 2010 database. The impact factors were merged into the spreadsheet of peer-reviewed LIS titles by matching on the ISBN. The ISI journal impact factor is based on the average number of times the articles in a journal have been cited by newer articles. ISI calculates the impact factor and the 5-year impact factor. The basic impact factor is derived by dividing the number of citations in the census year by the number of articles published in the previous two years. For example, an impact factor of 1.0 means that, on average, the articles published one or two years ago have been cited one time.26 The advantage of using the impact factors is that it is widely recognized, very easily retrieved, and updated annually. Many studies have used the impact factor as a reliable citation statistic; several of the citation studies dis- cussed in the literature review used it. The major disadvantage of the impact factor is that the library field is poorly covered by ISI; therefore, there are many journals that do not have an impact factor. To provide additional citation data, especially for journals not rated by Thom- son Reuters’ Journal Citation Reports®, the h-index was chosen. This calculation was developed by physicist Jorge Hirsch. He suggested that “a scientist has index h if h of his/her Np papers have at least h cita- tions each, and the other (Np − h) papers have no more than h citations each.” The calculation can be applied to journals as well as to authors. Although the h-index is available from the Web of Science, that score is limited to journals indexed by ISI.27 The h-index can also be calculated by using Harzing’s Publish or Perish soft- ware, which uses the citations per article in Google Scholar. The Harzing’s Publish or Perish software was downloaded,28 and each journal that was identified by any of the other criteria was searched using the “journal impact” tab. The search was limited to 2007 to 2011 to avoid Google Scholar’s maximum number of hits (1,000). In a few cases, this maximum was reached; the h-index for those titles could be slightly higher than the results indicate. In most cases, the journal name was searched in quotes, but titles with “and” or “&” were searched without quotes to be sure to obtain all articles published in the jour- nal. During the Publish or Perish searches, the results were ranked by h-index, so all articles above the h-index level could be scanned. For example, a search of “Journal of Information Technology” retrieved ar- ticles published in “Journal of Information Technology & Tourism” and several other journals starting with “Journal of Informa- tion Technology.” These were fairly easy to remove by scanning the publication and publisher field. The h-index was then automatically recalculated. The h-indexes were compiled from Publish or Perish searches for all titles that had at least one tally. Forty of the 88 titles that had an h-index higher than seven were given one tally. (Appendix A has a list of all titles searched, including the search string, notes on the search strategy, date searched, and the h-index. Titles exceeding the 1,000 hit limitation were noted, as the h-index could be slightly higher than the results indicated.) The h-index range was 0 to 46. The Pearson correlation between impact factor and h-index is .723. This high correlation was expected and is an indication of the reliability of this index. Other research has also found correlation between these indexes in the LIS field. Advantages of adding the h-index to the review is its availability for nearly every journal. Dis- advantages are that compiling the data takes about ten hours and that Google Scholar data can change from day to day. Findings The results of this tallying produced a working list of 90 titles. Five titles, which were out of scope for LIS, were removed; these were journals outside the LIS field where Purdue faculty had published, 84 College & Research Libraries January 2014 such as French Historical Studies. Two ceased titles were removed also. One title was removed because it only accepts sub- missions from members. The result was a list of 82 titles. (See table 3 for all titles and data in the study.) Of the 82 titles in this study, ten titles were not refereed; this left 72 titles to be sorted into the two tiers. Of the possible seven tallies, six journals received six or seven tallies each, identifying them as the top six journals: College & Research Libraries, Journal of the Medical Library As- sociation, Library Collections, Acquisitions, and Technical Services, Library Journal, Library Resources & Technical Services, and Reference & User Services Quarterly. Twelve titles received five tallies. These top 18 titles constituted the most impor- tant titles, or tier one titles. Eleven of the 18 were among the top journals in the literature review. (See bolded titles in the list below.) Several of the titles not identified in the literature review are in subdisciplines such as government documents, collection development, or medical librarianship. This met a goal of our committee to have the most important subdiscipline journals on the tier one list. The only title in the combined title list of expert opinion/ citation surveys’ top titles excluded from this list was Information Processing and Management. 1. Aslib Proceedings 2.

RQ (title changed to Reference & User Services Quarterly) Thirty-seven titles received between two and four tallies and were added as the tier two titles. Several of these titles represent sub-disciplines of LIS, such as archives, business, health, agricultural, or interlibrary loan. A few titles have an international scope. This variety strength- ens the tier two list. Some of the titles are from the information sciences side of LIS, which also adds breadth to the list. Sev- enteen titles that only received one tally were not added to any of the tiers. The 37 tier two titles, in alphabetical order, were: 1. Archival Science 2. Canadian Journal of Information and Library Science 3. College & Undergraduate Libraries 4. The Electronic Library: the interna- tional journal for the application of technology in information 5.

Online: Exploring Technology & Re- sources for Information Professionals 6. Public Libraries 7. School Library Journal Conclusions There was strong agreement between the titles on the tier one list and the top journals identified in the literature review. This gives credibility to the criteria used to compile the current list of the most influential journals in the field. Top LIS journals can be identified and ranked into tiers by compiling journals that are peer-reviewed and highly rated by the experts, have low acceptance rates and high circulation rates, are journals that local faculty publish in, and have strong citation ratings as indicated by an ISI impact factor and a high h-index using Google Scholar data. Some caution is in order about these ratings. The results of this methodology can and will vary from year to year, and even more frequently. The h-indexes can change daily, the impact factors and acceptance rates also vary from year to year. So the tier that any journal is in could change. This is desirable because, as journals become more influential, they will rise in the rankings. Practical Uses of the Results Librarian-authors at tenure-track institu- tions can apply these methods annually and create a ranked list of LIS journals. Or the methodology can provide a framework for the faculty to discuss the pros and cons of each criterion and cre- ate selection criteria specifically for their library. The Purdue Libraries’ tiered list does not match these findings exactly, but they were used in the final selection of titles. Librarian-authors, especially more experienced authors and those in tenured positions, could consider the tier one journals as the first choice for submis- sions. Librarians who are not publishing will find the ranked lists useful as a quick summary of the most influential journals in the field. The list could also be used by librarians who are asked to evaluate another librarian’s contribution to the literature by comparing the publications with the tiered lists. 86 College & Research
