[Factor impact and indexing in bibliographic databases: comparison of these quality criteria for the assessment of pharmaceutical journals].

In spite of limits, the impact factor (IF) of Journal Citation Reports (JCR) of Science Citation Index (SCI) edited by the Institute for Scientific Information (ISI) is the most currently used bibliometric factor by scientists. Otherwise, bibliographic systems select and index scientific journals with their own quality criterion. In order to bring scientists and information professionals some new journal evaluation developments, we studied and compared pharmaceutical journal IF and the number of bibliographic systems in which they were indexed. We firstly have given our definition of pharmaceutical journal and then evaluated these journals by giving one point each time they were indexed in one of the five following bibliographic systems: Index Medicus/Medline, Excerpta Medica/Embase, International Pharmaceutical Abstracts, Chemical Abstracts, Current Contents. We then compared their results with IF. We selected 292 journals: 14.4% scored 5 points, 22.3% scored 4 points, 27.7% scored 3 points, 18.8% scored 2 points, 16.8% scored 1 point. We also showed that the more journals scored highly, the more they had chances of being taken by JCR. We studied the first hundred journals indexed by JCR and having the highly IF: 31, 40, 21, 6 and 2 journals were respectively indexed by 5, 4, 3, 2 and 1 bibliographic systems. We showed that there was a significant difference between the two classifications. So, we can say that people who take IF as the one and only journal quality criterion have in fact a very partial representation of the edition of scientific papers.

Tests of methods for evaluating bibliographic databases: an analysis of the National Library of Medicine's handling of literatures in the medical behavioral sciences.

This article reports on five separate studies designed for the National Library of Medicine (NLM) to develop and test methodologies for evaluating the products of large databases. The methodologies were tested on literatures of the medical behavioral sciences (MBS). One of these studies examined how well NLM covered MBS monographic literature using CATLINE and OCLC. Another examined MBS journal and serial literature coverage in MEDLINE and other MBS-related databases available through DIALOG. These two studies used 1010 items derived from the reference lists of sixty-one journals, and tested for gaps and overlaps in coverage in the various databases. A third study examined the quality of the indexing NLM provides to MBS literatures and developed a measure of indexing as a system component. The final two studies explored how well MEDLINE retrieved documents on topics submitted by MBS professionals and how online searchers viewed MEDLINE (and other systems and databases) in handling MBS topics. The five studies yielded both broad research outcomes and specific recommendations to NLM.

A global overview of major or unique libraries, clearinghouses, and bibliographic databases in social gerontology.

Eighty-six major and/or unique information resources in social gerontology, mostly in the form of libraries, clearinghouses and other hybrid resources, and bibliogrphic databases were identified through an international survey. They are practically all located in the more developed countries, and the large majority are in the United States. A growing number are available in electronic format, facilitating direct end-user access. Significant information gaps continue to exist and access to the data resources of the northern hemisphere remains a major problem for developing nations.

Coverage and overlaps in bibliographic databases relevant to forensic medicine: a comparative analysis of MEDLINE.

This study was designed to make a comparative evaluation of the performance of MEDLINE in covering serial literature. Forensic medicine was chosen because it is an interdisciplinary subject area that would test MEDLARS at the periphery of the system. The evaluation of database coverage was based upon articles included in the bibliographies of scholars in the field of forensic medicine. This method was considered appropriate for characterizing work used by researchers in this field. The results of comparing MEDLINE to other databases evoked some concerns about the selective indexing policy of MEDLINE in serving the interests of those working in forensic medicine.

A primer for users of medical bibliographic databases.

A database is electronic information. Perhaps one of the most important information sources in medicine is that which is accessed electronically through a database named MEDLINE, the core medical literature published since 1966. MEDLINE is sold by three major vendors (BRS, Dialog, and the National Library of Medicine) to information experts and to medical experts. Information experts (librarians) and medical experts (physicians) can access MEDLINE by two different methods. This article discusses both and emphasizes use by the medical practitioner. An annotated guide to database vendors is provided, and guidelines are offered that will assist the physician in selecting equipment and assessing services.

Bibliographic databases: help in preparing reference lists.

Typing bibliography references is time consuming. It is also frustrating to have to retype references when you submit a manuscript to journals using different reference styles. Now you don't need to retype them. Computer programs have been developed which help you reorganize your references to many different styles. This experienced nurse author compares several of these programs for you.

The publication speed of information in bibliographic chemical databases.

The quality of bibliographic databases depends very much on the reliably fast follow-up of the pertinent literature. We have studied this quality feature of two important chemical bibliographic databases: Chemical Abstracts (CA) and Analytical Abstracts (AA). The follow-up rate (speed of information) of these databases has been determined with respect to 10 core journals in analytical chemistry. On the average the performance of Chemical Abstracts has been good over the past decade, while the formerly poor performance of Analytical Abstracts has improved considerably. Some quite unexpected nonuniformities can, however, still be detected in the publication time distributions of both databases.
