Finally, totally 138 graduate theses were elicited to analyze in regard to…

Discusses how historians can use computer searches to obtain bibliographic information. Historical databases which allow online searches are described. Sample searches are used to illustrate the characteristics of and processes involved in computer searching. (AM)

Describes compilation of data concerning pharmaceutical journal coverage in online databases which aid information providers in collection development and database selection. Methodology, results (a core collection, overlap, timeliness, geographic scope), and implications are discussed. Eight references and a list of 337 journals indexed online in…

This paper describes the experiences of researchers conducting research using an online course for the professional development of middle school mathematics and science teachers. The paper also offers recommendations to developers of course management systems (CMS). The online course focused on strategies that promoted gender equitable pedagogy…

This study conducted to determine representation impact on information items retrieval in terms of precision and recall performance and overlap used the INSPEC "Computers and Control Abstracts" loaded on DIATOM, an online retrieval system based on DIALOG, as the database to be searched. Sixty-nine users provided 84 queries which were…

An iterative method for information retrieval is presented using searchonyms found from previously retrieved set of documents in query expansion. Large operational bibliographic databases are used to simulate behavior of this method which selects most informative features as searchonyms to be used in query reformulation. Ten references are listed.…

Presents analysis of online search patterns within user searching sessions of National Library of Medicine ELHILL system and examines user search patterns on the CATLINE database. Data previously analyzed on MEDLINE database for same period is used to compare the performance parameters of different databases within the same information system.…

Internet resources in Russia and the United States that deal with education are compared. Resources in both countries are listed for the following areas: (1) search engines; (2) specialized databases with limited access; (3) libraries; (4) on-line databases and information systems; (5) books on education, educational journals, and newspapers (in…

Evaluates overlapping coverage of 21 scientific databases used in 10 online pesticide searches in an attempt to identify minimum number of databases needed to generate 90 percent of unique, relevant citations for given search. Comparison of searches combined under given pesticide usage (herbicide, fungicide, insecticide) is discussed. Nine…

The low rate of relevant titles (fewer than 50 percent) retrieved by online searching of keywords in titles in study conducted at the Mechanized Information Center, Ohio State University, is attributed to three sources: titles themselves, user ignorance of subject vocabulary, and general language problems. Eight references are cited. (EJS)

A study of periodicals usage conducted at I.D. Weeks Library, University of South Dakota, used computerized databases to isolate journals important to individual departments and establish criteria for periodical subscription budget cuts. Three search methods used and costs incurred are outlined. Four references and search examples are provided.…

Describes method of selecting document groups for automation developed by Advanced Document Management Systems staff at Westinghouse Water Reactor Divisions. Criteria for inclusion of document in database, survey questionnaire, a weighting formula to assign priorities (critical, frequency of retrieval, quality assurance, interdivisional use), and…

Implementation of relevance feedback explored here demonstrates feasibility of query reformulation for boolean retrievals from online databases. Improvements to a term prevalence formula used in earlier research are presented, along with experimental results that confirm crucial role of term weights in relevance feedback. Seven references are…

Retrievability of titles of 152 periodicals were compared in a fixed-length algorithmic search (Library Computer System) and a keyword search (Washington Library Network) to determine which type of search algorithm is more successful with titles of varying lengths. Three references and a list of English language stopwords are appended. (EJS)

Presents results of study undertaken at Census Bureau Library to determine which databases would be most productive and how they can be effectively searched to meet demands of bureau staff for literature on statistical research and methodology. Database selection in DIALOG Information Retrieval Service and journal coverage are noted. (EJS)
