Dissertations-An Online Dilemma 

Donald K. Hartman and Manuel D. Lopez 

There are few bibliographic aids available to the 
online searcher who has questions concerning 
dissertations and theses and the extent of their 
coverage by the various databases. A compari-
son of two databases concerned with this "for-
mat" material is not completely reassuring, 
while the survey of the individual databases 
cited did provide useful information for the on-
line searcher and contributes to reducing the 
uncertainty of the situation. 

THE PROBLEM 

That uncomfortable feeling of uncer-
tainty is back. As an academic librarian, 
information broker, or online searcher in a 
corporate structure you have just com-
pleted a computerized search. The cita-
tions are relevant but include several ref-
erences to dissertations and/or theses. 

Does t~at mean you don't have to search 
Dissertation Abstracts Online? Questions 
nag. When did the database just searched 
start to include dissertations/theses? Were 
citations to dissertations added retrospec-
tively? What about foreign dissertations? 
Are they included? If so, which countries? 
Just what percentage of the database is 
dissertations? The directory Computer-
Readable Databases does indicate percent-
ages but only in combinations of formats. 
What were the criteria used for selection of 
dissertations? Who assigned the subject 
headings/descriptors? The author, data-
base personnel, or others? Was a thesau-
rus used? If so, which one? 

THE SEARCH FOR ANSWERS 

A search by document type ( dt =theses? 
or dt=dissertation? or dt=doctoral?) of 

Donald K. Hartman and Manuel D. Lopez are reference librarians at the State University of New 
York, Buffalo, New York 14260. 



the Database of Databases (file 230 on Dia-
log) indicated that over 300 databases in-
cluded dissertations and/or theses. The 
search was refined to those vendors 
thought to be most heavily used by online 
searchers: BRS, Dialog and SDC (the 
search procedure is shown in figure 1). 
This ·reduced the number of databases 
listed as having dissertations or theses, by 
document type, to 153. Questionnaires 
were sent to 142 database producers. Be-
cause seventeen of the cited databases 
were subsets of larger ones (e.g., Agricul-
tural Abstracts, which is a subset of CAB 
Abstracts), the questionnaires sent to the 
142 producers actually involved a total of 
159 databases. There were 106 returns: 66 
respondents indicated that disserta-
tions/theses were part of their databases, 
40 database producers stated that disserta-
tions and theses were not included in their 
services. The initial search strategy pro-
vided citations to a number of databases 
that in fact did not include disserta-
tions/theses. This may have been the 
result of the use of a standardized 
phrase-''Monographs, proceedings, 

Research Notes 79 

theses" -in Database of Databases to de-
scribe the scope of a particular database 
when it did not include one or more of the 
formats covered by that phrase. 

A search of Knowledge Industry Publica-
tions Database (file KIPD on BRS) produced 
69 citations to databases having disserta-
tions or theses as a document type (see fig-
ure 1). Fifty of these databases had been 

.listed in the first search. Thirty-two of 
these had responded to the first question-
naire, and among these respondents, 26 
included the required materials. Ques-
tionnaires were sent to the remaining 19 
database producers; all 13 respondents 
did include dissertations/theses. 

It is notable that the search of Database of 
Databases did not provide a reference to 
Dissertation Abstracts Online, which in-
cludes about 99 percent of American dis-
sertations (more than 850,000 since 1862), 
thousands of Canadian dissertations, and 
those from about 200 foreign universities. 
While author and keyword in-title index-
ing in Dissertation Abstracts Online pro-
vides adequate access with some "noise" 
or unwanted citations, the practice of hav-

ing authors assign subject headings can 
result in "lost" references. Considering 
the volume of research and information 
available in this "format" database and 
the scope and limitations of other data-
bases containing dissertations and ab-
stracts, the online searcher should not ig-
nore this particular resource. 

findings, the searcher should be wary of 
assuming that a database with a large per-
centage of dissertations is comprehensive. 
For example, dissertations in The Middle 
East: Abstracts and Index represent only 
about .025 percent of the database, but 
that percentage represents 300-400 disser-
tations about this very specific topic 
within an annual volume of some 16,000 
citations and is quite comprehensive in 
this area. Also, the producers of this data-
base manually review Dissertation Ab-
stracts International, thus avoiding the va-
garies of subject headings and keyword 
indexing. This approach has disadvan-
tages as well. However, because the pro-
ducers limit themselves to DAI, significant 
research may be overlooked, as not every 
university (e.g., Harvard and, until re-
cently, University of Chicago) participates 

Other differences between the Database 
of Databases (list A) and Knowledge Industry 
Publication Database (list B) are indicated in 
table 1. While the B list was numerically 
smaller, 66 percent of its cited databases 
did, in fact, include dissertations/theses, 
while only 42 percent of the databases in 
list A made the same claim. 

The file-by-file results of our survey may 
be useful in resolving some of the prob-
lems of the online searcher. These results 
are shown in table 2. In interpreting these

in the program. The problem is com-
pounded by the fact that many institu-
tions that are project members do not sub-
mit all of their dissertations. 

Survey results indicate that in the area 
of dissertations/theses, caution should be 
the prime guide of the online searcher.

The largest microfiche collection 
on the Vietnam War available. 

This collection is a resource that sheds light on the history of the Vietnam 
conflict and some of the questions surrounding it by presenting materials 
previously difficult to access. The History of the Vietnam War spans 21 
years of history and includes 365,000 pages of documents, newspapers, 
periodicals, photographs, monographs, maps and graphs collected 
by Douglas Pike, Director of the Indochina Archives at the University 
of Califomia, Berkeley.

a U.S. Foreign Service Officer during the war, he was considered the

Peking, Moscow, Tokyo, Australia and Westem Europe. Many documents 
were gathered through personal contacts and are not available 
elsewhere. 

The History of the Vietnam War microfiche collection is a valuable 
addition for libraries and research centers which serve students 
and researchers of 20th Century American and Indochinese history, 
intemational or U.S. law, economics, political science, govemment,
