Articles 50 Years of ITAL/JLA: A Bibliometric Study of Its Major Influences, Themes, and Interdisplinarity Brady Lund INFORMATION TECHNOLOGY AND LIBRARIES | JUNE 2019 18 Brady Lund (blund2@g.emporia.edu) is a PhD Student at Emporia State University’s School of Library and Information Management. ABSTRACT Over five decades, Information Technology and Libraries (and its predecessor, the Journal of Library Automation) has influenced research and practice in the library and information science technology. From its inception on, the journal has been consistently ranked as one of the superior publications in the profession and a trendsetter for all types of librarians and researchers. This research examines ITAL using a citation analysis of all 878 peer-reviewed feature articles published over the journal’s 51 volumes. Impactful authors, articles, publications, and themes from the journal’s history are identified. The findings of this study provide insight into the history of ITAL and potential topics of interest to ITAL authors and readership. INTRODUCTION Fifty-one years have passed since the first publication of the Journal of Library Automation (JLA), the precursor to Information Technology and Libraries (ITAL), in 1968: 51 volumes, 204 issues, and 878 feature articles. Information technology and its use within libraries has evolved dramatically in the time since the first volume, as has the content of the journal itself. Given the interdisciplinary nature of Library and Information Science (LIS) and ITAL, and the celebration of this momentous achievement, an examination of the journal’s evolution, based on the authors, publishers, and works that have influenced its content, seems apropos. The following article presents a comprehensive study of all 7,575 references listed for the 878 articles (~8.6 refs/article average) published over ITAL’s fifty years, identifying those authors and publishers whose work has been cited the most in the journal and major themes in the cited publications, and an evaluation of the interdisciplinarity of references in ITAL publications. This study not only frames the history of the ITAL journal, but demonstrates an evolution of the journal that suggests new paths for future inquiry. CONCEPTUAL FRAMEWORK A major influence for the organization and methodology of this paper is Imad Al-Sabbagh’s 1987 dissertation from Florida State University’s School of Library and Information Studies, The Evolution of the Interdisciplinarity of Information Science: A Bibliometric Study.1 In this study, Al- Sabbagh sought to examine the interdisciplinary influences on the burgeoning field of information science by examining the references of the Journal of the American Society of Information Science (JASIS), today known as the Journal of the Association for Information Science and Technology (JASIST). In Al-Sabbagh’s study, a sample of ten percent of JASIS references was selected for examination.2 The references were sorted into disciplines based on the definitions supplied by INFORMATION TECHNOLOGY AND LIBRARIES | JUNE 2019 19 Dewey Decimal Classification categories, with the percentages compared to the total number of the sampled references to derive percentages (e.g., if 150 references of 1,000 total JASIS references examined belonged to the category of library science, then 15 percent of references belonged to library science, and so on for all disciplines). The present study deviates slightly from Al-Sabbagh’s in that it does not use a sampling method. Instead, all 878 articles published in JLA/ITAL and their 7,575 references will be examined. The categories for disciplines, instead of being based of Dewey Decimal, will be based on definitions derived from Encyclopedia Brittanica, and will include new disciplines that were not used in Al-Sabbagh’s original analysis, such as Information Systems and Instructional Design. 3 Additionally, the major authors, publishers, and articles cited throughout JLA/ITAL’s history will be identified; this was not done in Al-Sabbagh’s study, but will likely provide additional beneficial information for researchers and potential contributors to ITAL. ITAL is an ideal publication to study using Al-Sabbagh’s methodology, in that it is affiliated with librarianship and library science but, due to its content, is also closely associated with the disciplines of information science, computer science, information systems, instructional design, psychology, and many others. ITAL is likely one of the more interdisciplinary journals to still fall within the category of “library science.” In fact, as part of Al-Sabbagh’s 1987 study, he distributed a survey to several prominent information science researchers, asking them to name journals relevant to information science (this method was used to determine that JASIS was the most representative journal for the discipline of information science). On the list of 31 journals compiled from the respondents’ rankings, ITAL ranked as the seventh most representative journal for information science, above Datamation, Scientometrics, JELIS, and Library Hi-Tech.4 This shows that, for a long time, ITAL has been considered as an important journal not just in library science, but in information science and likely beyond. Key Terminology While the findings of this study are pertinent to the ITAL reader, some of the terminology used throughout the study may be unfamiliar. To acclimate the reader to the terminology used in this study, brief definitions for key concepts are provided below. Bibliometrics. “Bibliometrics” is the statistical study of properties of documents.5 The present study constitutes a “citation analysis,” a type of bibliometric analysis that examines the citations in a document and what they can reveal about said document. Cited Publications. “Cited Publications” are the references (“publications”) listed at the end of a journal article.6 The purpose of Al-Sabbagh’s study (and the present study) is to analyze these cited publications to determine what disciplines influenced the research published in a specific journal. This bibliometric analysis methodology is distinct from those that examine the influence of a specific journal on a discipline (i.e., the present study looks at what disciplines influenced ITAL, not what disciplines are influenced by ITAL). Discipline. In this study, the term “discipline” is used liberally to refer to any area of study that is presently or was historically offered at an institution of higher education (sociology, anthropology, education, etc.). In this study, library science and information science are considered as distinct disciplines (as was the case with Al-Sabbagh’s study).7 As discussed in the methodology section, the names and definitions of disciplines are all derived from the Encyclopedia Britanica. 50 YEARS OF ITAL/JLA | LUND 20 https://doi.org/10.6017/ital.v38i2.10875 LITERATURE REVIEW The type of citation analysis used by Al-Sabbagh and as the basis of the current study are used frequently to examine the interdisciplinarity of library and information science and specific LIS journals, as noted by Huang and Chang.8 Tsay used a similar methodology to Al-Sabbagh to examine cited publications in the 1980, 1985, 1990, 1995, 2000, and 2004 volumes of JASIST. In this study, the researcher found that about one-half of the citations in JASIST came from the field of LIS.9 Butler examined LIS dissertations using a similar approach, finding that about 50 percent of the cited publications in the dissertations originated in LIS, with education, computer science, and health science following in the second, third, and fourth positions.10 Chikate and Paul and Chen and Liang conducted similar studies of dissertations in the India and Taiwan.11 Each study found different degrees of interdisciplinarity, possibly indicating a fluctuation within the discipline of LIS based on publication type, country of origin, etc. for the publications used in the study. Several researchers have used these methods recently to examine library and information science journals, such as Chinese Librarianship,12 Pakistan Journal of Library and Information Science,13 Library Philosophy and Practice,14 and the Journal of Library and Information Technology.15 These studies are more common for journals published outside of the United States, but there is no reason why the methodology would not hold true for a U.S.-based journal like ITAL. Recently, publications in a wide array of fields have used similar methodologies as Al-Sabbagh to evaluate interdisciplinarity in a discipline. Ramos-Rodriguez and Ruiz-Navarro (2004) examined reference trends in the Journal of Strategic Management.16 Fernandez-Alles and Ramos-Rodriguez (2009) conducted a bibliometric analysis to identifying those publications most frequently cited in the journal Human Resource Management.17 Crawley-Low (2006) used a similar methodology to identify the core (most frequently cited) journals in veterinary medicine from the American Journal of Veterinary Research.18 These studies show a growing interest in the use of citation analysis to present new information about a publication to potential authors, editors, and readers. Jarvelin and Vakkari (1993) noted trends in LIS from 1965 to 1985 based on an examination of cited publications in LIS journals. The authors noted a trend in interest in the topic of information storage and retrieval, with a de-emphasis on classification and indexing and a strengthened emphasis on information systems and retrieval.19 This study deviated from Al-Sabbagh and related studies of interdisciplinarity—though it employed a similar methodology—in that it examined trends or subtopics within the discipline of LIS. Though it is not a primary focus of the present study, the use of subtopics to further divide the discipline of library science and examine what aspects (management, technology, cataloging, reference) of the discipline are the focus of cited publications is incorporated in several tables in the results section. METHODS All references from the 878 articles published in the JLA/ITAL journals (n=7,575) were transcribed to an Excel spreadsheet for analysis (this spreadsheet can be found as a supplemental file [https://ejournals.bc.edu/index.php/ital/article/view/10875/9469]). The spreadsheet includes separate columns for primary author, title, publisher, and discipline of each reference. The list of disciplines with their definitions, derived from Encyclopedia Brittanica, is displayed in table 1 below. INFORMATION TECHNOLOGY AND LIBRARIES | JUNE 2019 21 Table 1.

To determine the discipline in which a cited publication would be classified, the researcher used the cited publication’s title, abstract, and journal to select the most appropriate discipline from the table. In those cases where a source could not be easily identified as falling within one specific discipline, the researcher conferred with additional reviewers (professional librarians) to determine the best fit. INFORMATION TECHNOLOGY AND LIBRARIES | JUNE 2019 23 Several analyses of this data were conducted to explore various aspects of JLA/ITAL’s publication history. For the complete data of the publication’s 51 volumes, the top ten most referenced authors, articles, publishers (journals/publishing houses/organizations/websites), and disciplines were identified with the aid of Excel’s functions. The same was done separately for both the JLA’s 14 volumes and ITAL’s 37 volumes. This will allow for the comparison of the journal before and after the 1982 rebranding. The 51 volumes of JLA/ITAL were also divided into the five decades of its history: 1968-77, 1978-87, 1988-97, 1998-2007, 2008-18 (eleven volumes instead of ten). For each of these decades, the top ten authors, publishers, and disciplines were identified. For each of the three categories, a table was created to show the top ten of each decade side-by-side. Lastly, the titles of the 7,575 cited publications in JLA/ITAL articles were examined using a content analysis, to identify major concepts and themes that appear to have influenced JLA/ITAL articles. NVivo content analysis software was utilized for this analysis. Titles were fed from the Excel spreadsheet into the NVivo software, and the word frequency tools were used to identify the most frequently used terms and “generalizations,” or types or themes of statements in the titles.20 RESULTS Table 2 displays the top ten most-cited authors, articles, publishers/publications, and disciplines throughout ITAL’s fifty-year history. Among the authors, four of the top six are associated with two institutions: Library of Congress and OCLC. There are four corporate or nonprofit organizations, three academics (associated with institutions of higher education), two women and four men. Of the top ten articles, eight were published before 1973; three were published in JLA/ITAL and five were published in journals versus five in other (non-journal) publications. Of the top ten publishers, seven are journals; five of the publishers are directly associated with library science. Within the disciplines, LIS represents 60 percent of the total. There are 31 total disciplines represented throughout the 51 volumes, a greater number of disciplines than identified in Al-Sabbaugh’s study of JASIST. Table 3 displays the results for JLA. JLA emerged at the same time as the Machine-Readable Catalog (MARC) and OCLC, and this is evident in the authors, articles, and publishers cited in the journal. During this phase of the journal’s history, the top three authors—Fred Kilgour, the Library of Congress, and Henriette Avram—dominated the citations. These three authors were cited more than the next seven combined (143 to 101). The cited publications during this period reflected a focus on systems, corporate, and government publications. Results for the 37 volumes of ITAL are displayed in table 4. During this period, Marshall Breeding emerged as one of the biggest influences on information technology and libraries. All but two of the top articles (Larson and Bizer) were written before 1985. While six publishers were the same as with JLA, three of these six (Library of Congress, Association for Computing Machinery, and College and Research Libraries) changed position in the top ten. The disciplines of systems, psychology, educational and instructional design rose, while government, corporate, management, linguistics, and electrical engineering dropped; library science, information science, and computer science remained at the top. 50 YEARS OF ITAL/JLA | LUND 24 https://doi.org/10.6017/ital.v38i2.10875 Table 2.

For the first two decades, Fred Kilgour was a dominate influence, receiving 15 more citations than the next closest author (the Library of Congress). In the third decade, Kilgour dropped entirely from the top ten and was supplanted at the top spot by Karen Markey, professor at the University of Michigan. During the fourth decade, in the wake of CIPA and the U.S. Patriot Act, the Library of Congress rose to the top spot and John INFORMATION TECHNOLOGY AND LIBRARIES | JUNE 2019 27 Bertot and Paul Jaeger, who wrote extensively on these topics and their legal, social, and administrative implications, rose up the list. Web resources, such as Google, also began to emerge in the fourth decade. In the final decade, Breeding, who writes on library systems as well as information technology in general, rose to the top spot. Tim Berners-Lee, one of the pioneers of the Internet and linked data, took the second spot. Jakob Nielson, known for his contributions to usability testing, appears in the top three of the rankings for both the fourth and fifth decade. Only the Library of Congress and American Library Association appear in the top ten list for all five decades. Table 5.

During that decade, ACM and JASIST rose above ITAL, and Library Journal and websites (websites are considered in this study as a collective group) emerged on the list. Library Journal was a frequently used source for Bertot and Jaeger, who authored several ITAL articles during this period. There were also more articles about the Internet, digital libraries, Google and Google Scholar, and the future of libraries during the fourth decade. JASIST appears in the top four of every decade but has declined in the fifth decade of ITAL. OCLC, IBM, College and Research Libraries, Cataloging and Classification Quarterly, Journal of Academic Librarianship, Library Resources and Technical Services, and Library Hi-Tech all appear in multiple decades of this list.

Government and corporate (IBM particularly) were important in the first three decades but were replaced by instructional design and education in the final two decades. Sociology appears in four of five decades, while psychology appears in three of five. In the first two decades, electrical engineering (as it applied to the design of computer systems) rounded up the top ten; law emerged in decade four, following CIPA and the INFORMATION TECHNOLOGY AND LIBRARIES | JUNE 2019 29 Patriot Act; in the final decade, with the discussion about Encoded Archival Description in ITAL, archival science rose to the tenth spot.

Compared to the first decade, the fifth decade saw greater diversification of subtopics under library science, which led to “information science” supplanting “library science—technology” in the top spot. Instructional design and archival science emerged from disciplines not discussed in the first decade to become some of the most important disciplines of the fifth decade. The library science subtopics of accessibility and teaching grew significantly as the roles of the librarian evolved. 50 YEARS OF ITAL/JLA | LUND 30 https://doi.org/10.6017/ital.v38i2.10875 Table 8.

Library is the most common theme and term. The library catalog, and the associated concept of the Integrated Library System (ILS), influence the second and third themes. “Online” is an interesting theme/term for the different ways in which it was used throughout the history of the journal. In the early years, “online” was used to refer to the retrieval of computerized bibliographic information; in later years, “online” came to refer almost exclusively to the use of the World Wide Web. Rounding out the top ten terms are several that associated with the study of information science: data, bibliography, and retrieval. Finally, table 10 depicts the top ten themes for each of ITAL’s five decades. Libraries remained at the top for all decades; the second spot, however, shifted dramatically. In the first decade, with MARC being a major topic of discussion, “system” and “catalog” rose to the top. In decades two and three, with the melding of the disciplines of library science and information science, “information” rose to the top. In the final two decades, the World Wide Web was influential on the ITAL discourse. Users, usability, and accessibility remain an important theme throughout the history of the journal. 50 YEARS OF ITAL/JLA | LUND 32 https://doi.org/10.6017/ital.v38i2.10875 Table 9.

Throughout the journal’s history, there has been an emphasis on library systems, particularly systems for library cataloging. Recently, however, there has also been an emphasis on technology, law, and the library as well as instructional technology, teaching, and the library. ITAL authors take the majority of their citations/ideas from other ITAL articles, JASIST, ACM, and other library technology (Library Hi- tech, D-Lib) and academic librarianship (College and Research Libraries, Journal of Academic Librarianship) journals. Some of the major authors to read to familiarize oneself with the history and themes of the ITAL publication include Fred Kilgour, Henriette Avram, Karen Markey, and Marshall Breeding. These are some findings that potential ITAL authors may find practical use while preparing crafting their research and writing. With ITAL having a sustained role as a leading publication in library and information science, this study may have some generalizable findings for the discipline. In 2015, Richard van Noorden produced an interactive chart of the interdisciplinarity of a variety of disciplines, based on data from Web of Science and the National Science Foundation.22 If ITAL is considered representative of a sub-discipline called “library and information science—technology,” it can be compared to the interdisciplinarity of the disciplines listed in van Noorden’s study. In the last decade of ITAL, 45.4 percent of citations came from outside of LIS. Compared to van Noorden’s findings, only 42 of 144 (29 percent) “fields” (or “disciplines,” as they have been referred to as in this study) have a higher proportion of references to outside disciplines. This LIS-Tech sub-discipline would have a level of interdisciplinarity comparable to the fields of oceanography, botany, philosophy, history, and psychology, and on-par with the average for all social sciences.23 This shows that the discipline certainly has its own proprietary knowledge-base to build upon, but also values the contributions of knowledge from other disciplines. Though it is not necessarily the purpose of this study to examine the influence of ITAL on other journals and within the discipline of LIS, some of this information can be gathered rather easily from Google Scholar (by searching for the journal and comparing the number of citations for each article, as displayed by Scholar) and is worth sharing. Table 11 shows the top ten most-cited articles published over the history of JLA/ITAL, with McClure’s 1994 article “Network Literacy: A Role for Libraries,” receiving the most references of any article published in the journal. Three ITAL articles have been cited by articles which themselves have over 1,000 citations, including one article (2007’s “Checking Out Facebook.com”) that has been cited by an article which itself has been cited over 10,000 times. Fifty-seven ITAL articles have at least 57 citations, giving the journal an h-index24 of 57. 50 YEARS OF ITAL/JLA | LUND 34 https://doi.org/10.6017/ital.v38i2.10875 Table 11.

This bibliometric analysis was conducted in the “old-fashioned” way, using Excel and hand-typing out all 7,575 cited publications. This was deemed the most effective way to collect the data, based on the availability of ITAL journal, but did take a great deal of time. To save time in recording data, only the first author for each cited publication was listed and no publication dates were collected, nor were abstracts retained and analyzed (which may provide additional compelling details about the content of these cited publications). Greater validity for the assignment of disciplines to cited publications may be achieved by having a large team of researchers for analysis, or using multiple researchers for all citations, not just those that the first researcher deems questionable.25 As with a content analysis, independent review of data and comparison and compromising of coding is likely to provide the most consistent and accurate results. INFORMATION TECHNOLOGY AND LIBRARIES | JUNE 2019 35 CONCLUSION Fifty-one volumes of the Journal of Library Automation/Information Technology and Libraries have been published, over which time library technology has evolved from early-MARC, a time in which the exceptional library would have perhaps a single computer for “online retrieval,” to the Internet Age, characterized by personal computing, library management systems, and technology-aided instruction. As time has passed, many of the major influences on the journal have changed, yet the journal has remained one of the most influential for library and information science technology. Increased interdisciplinarity in cited publications and new directions in information law and education offer new directions as the journal enters its sixth decade.
