Systematic literature reviews are common in social research for integrating and synthesising existing research. This paper argues that the outcomes of such reviews are affected by the choice of bibliographic databases. It presents evidence of substantial variation across three large electronic databases (Scopus, Web of Science and EBSCO) in a…

A retrospective analysis published by the German Institute for Quality and Efficiency in Health Care (IQWiG) in 2018 concluded that no filter for non-randomized studies (NRS) achieved sufficient sensitivity ([greater than or equal to] 92%), a precondition for comprehensive information retrieval. New NRS filters are therefore required, taking into…

This article presents the results of a study of academic e-books that compared the metadata and search results from major academic e-book platforms. The authors collected data and performed a series of test searches designed to produce the same result regardless of platform. Testing, however, revealed metadata-related errors and significant…

In spite of its popularity, keyword search mode has not been standardized. Though information professionals are quick to adapt to various presentations of keyword search mode, novice end-users may find keyword search confusing. This article compares keyword search mode in some major reference databases and calls for standardization. (Contains 3…

The use of bibliographic management software and its internal search interfaces is now pervasive among researchers. This study compares the results between searches conducted in academic databases' search interfaces versus the EndNote search interface. The results show mixed search reliability, depending on the database and type of search…

Content-enriched metadata in bibliographic records is considered helpful to library users in identifying and selecting library materials for their needs. The paper presents a study, using circulation data from a medium-sized academic library, of the effect of content-enriched records on library materials usage. The study also examines OPAC search…

This paper presents a comparative evaluation of Google Scholar and 11 other bibliographic databases (Academic Search Elite, AgeLine, ArticleFirst, EconLit, GEOBASE, MEDLINE, PAIS International, POPLINE, Social Sciences Abstracts, Social Sciences Citation Index, and SocINDEX), focusing on search performance within the multidisciplinary field of…

In this article, the authors compared the MLA International Bibliography database (MLAIB) across five vendor platforms to determine how and why seemingly comparable searches produced varying results. A number of tests were conducted using a variety of fields, terms, and parameters, and examples of results are provided. The authors' findings are…

The Educational Resources Information Center (ERIC) is a national information system sponsored by the Department of Education. Traditionally, access to ERIC materials has been through the printed indexes "Resources in Education" (RIE), a guide to documents and research reports, and "Current Index to Journals in Education"…

Describes the development and functions of a text retrieval program that makes extensive use of the best match model of document retrieval rather than the Boolean model. The use of the program in teaching and research at the University of Sheffield is summarized. (24 references) (CLB)

Presents an online search strategy to help find pairs of medical literatures that are logically related but non-interactive, meaning the two pairs have no articles in common, do not cite each other, and are not co-cited. Each stage of the search strategy is described and favorable results are discussed. (four references) (CLB)

Provides excerpts from interviews with expert online searchers to be published in a book entitled "Secrets of the Super Searchers" in the fall of 1993. Planning search strategies is the focus; and topics addressed include methods of planning searches, broad versus narrow searches, and building with component parts. (EAM)

Describes methods for applying natural-language processing for automatic concept-based indexing of full text and methods for exploiting the structure and hierarchy of full-text documents to a large collection of full-text documents drawn from the Health Services/Technology Assessment Text database at the National Library of Medicine. Examines how…

Discusses ways in which using mathematical symbols to search online bibliographic databases in scientific and technical areas can improve search results. The representations used for Greek letters, relations, binary operators, arrows, and miscellaneous special symbols in the MathSci, Inspec, Compendex, and Chemical Abstracts databases are…

Examines the distribution of bibliographic records in online bibliographic databases using 14 different search topics on DIALOG. Discusses the presence of duplicate records and problems with lexical ambiguity, and concludes that the number of databases needed for searches with varying complexities of search strategies is much more topic dependent…
