The current evaluation and comparison system of scientific production by impact factor has been criticised from different perspectives in recent years, and has ensured that publishing in high-impact journals does not necessarily imply that works are quality works. Many of these jobs are mostly not cited or, in the best of cases, only a very small…

As the Web is becoming a powerful new medium in scientific publication and scholarly communication, citation indexing has found a new application in the digital environment. The authors reviewed the new developments in Web-based citation indexing and conducted a case study in three major citation search tools, "Web of Science", "Scopus" and…

The goal of this study was an appraisal of indexing coverage for the interdisciplinary field of toxicology. Information of research significance was limited to primary literature, defined as published documents containing original data from experimental work or case studies. (6 references) (Author/NH)

Provides a chart showing differences (as of November 1979) in basic indexes for a number of databases that are available on two or more systems, such as DIALOG, ORBIT, and BRS. For each database, fields that are searched when a single unqualified search term is entered are listed. (Author/JD)

How do salaries of elementary and middle school principals compare with those of other administrators and classroom teachers? Are increases in salaries of principals keeping pace with increases in salaries of classroom teachers? And how have principals' salaries fared over the years when the cost of living is taken into account? This article…

This paper compares the subject indexing on articles pertaining to Immanuel Kant, agriculture, and aging that are found simultaneously in Humanities Index, Academic Search Elite (EBSCO) and Periodicals Research II (Micromedia ProQuest), in order to show that there are substantial variations in the depth and quality of indexing in these databases.…

Reports on a study that examined scope notes added to subject headings in the Library and Information Science Abstracts (LISA) Online User Manual. Types of messages conveyed by scope notes and word patterns within the notes are identified, and comparisons between the 1982 and 1987 editions of the manual are made. (16 references) (MES)

Describes the different approaches taken by the Chemical Abstracts Services database, which abstracts and indexes chemical publications, and the Belstein Handbook of Organic Chemistry database, which produces a collection of critical reviews. The resulting content of the databases and their ability to meet the needs of different users are…

Discusses strengths of abstracting and indexing services (subject coverage, resolution of language problems, systematic indexing) and summarizes sources, countries of origin, languages, total coverage, and indexing of four scientific and technical services--Biosis, Engineering Information, Inspec, Chemical Abstracts Service. Characteristics of…

Three online databases that provide information on regional, state, and local business news are compared in terms of publications indexed, indexing guidelines, record structure, span of coverage, currency, and availability. (CLB)

Intended to provide the nursing community with a comparative analysis of four major computerized document retrieval systems and one manual system providing coverage of the nursing literature, this study compares the indexing vocabulary, database coverage, and retrieval performance of the Educational Resource Information Center (ERIC),…

Compares OCLC, WLN, and RLIN in terms of the composition of the databases, indexes and searching, special uses for public services, costs, and documentation. Selected bibliographies of general public service uses and interlibrary loan applications are provided. (CLB)

Examines online and printed equivalents of selected government documents indexes to compare the recall, precision, overlap, and cost effectiveness of online and manual searching. Indexes studied were the Monthly Catalog, CIS (Congressional Information Service) Index, and Government Reports Announcements and Index. (CLB)

This book provides guidelines for evaluating a variety of database types, including abstracting and indexing, directory, full-text, and page-image databases available in online and/or CD-ROM formats. The book discusses the purpose and techniques of comparing and evaluating the most important characteristics of textual databases, such as their…

With "Chemical Abstracts" and "Science Citation Index" both now available for citation searching, this study compares the duplication and uniqueness of citing references for works of chemistry researchers for the years 1999-2001. The two indexes cover very similar source material. This analysis of SciFinder Scholar and Web of…
