ABSTRACT The Library of Congress Subject Headings have been criticized for containing biased subject headings. One leading critic has been Sanford Berman, whose 1971 monograph Prejudices and Antipathies: A Tract on the LC Subject Heads Concerning People (P&A), listed a number of objectionable headings and proposed remedies. In the decades since P&A was first published, many of Berman's suggestions have been implemented, while other headings remain unchanged. This paper compiles all of Berman's suggestions and tracks the changes that have occurred; a brief analysis of the remaining areas of bias is included. 相似文献

This article provides a brief history of the development of the MEDLINE database and its huge impact within the UK, from its inception to the present time. The origins of MEDLINE can be traced back to a collection of books in the US Surgeon General's Office during the American Civil War and John Shaw Billings' decision, during 1867, to make this Library as complete as possible. From these beginnings, Index Medicus was developed in the early years of the 20th century, and electronic versions of the database began with the computerized on-demand search service MEDLARS in 1964 and then via CD-ROM and Internet Grateful Med to the web-based and free-to-all service, PubMed, in 1997. The response to PubMed was immediate and startling with usage increasing from 7 million searches per annum in 1996 to 400 million searches per annum in 2001 and the service continues to improve. MEDLINE providers are now offering mapping of natural language queries to the sophisticated indexing vocabulary (Medical Subject Headings, MeSH) and the provision of specific filters for different types of publication to improve searching efficiency, as well as links to full-text versions of the papers where available. The next steps are likely to involve an increased blurring of database and full-text boundaries, incorporating seamless access to the best available evidence within MEDLINE and a wide range of other information resources within a single search and to an increasing amount of full-text via various open-archive initiatives. As ever, the US National Library of Medicine is in the vanguard of research and further applications of its MEDLINE database for users within the UK will be awaited with great interest. 相似文献

The constantly changing metadata landscape means that libraries need to re-think their approach to standards and subject analysis, to enable the discovery of vast areas of both print and digital content. This article presents a case study from the British Library that assesses the feasibility of adopting FAST (Faceted Application of Subject Terminology) to selectively extend the scope of subject indexing of current and legacy content, or implement FAST as a replacement for all LCSH in current cataloging workflows. 相似文献

The latest release of GRATEFUL MED offers medical libraries an opportunity to monitor searching patterns of end users searching the databases of the National Library of Medicine (NLM). A GRATEFUL MED use log records information from each search session. Analysis of the log from a recent beta test program at the Welch Medical Library indicates that most NLM searches occur in the MEDLINE database. Moreover, the study reveals that searchers overlook many user-friendly features of the program. Evaluation of the use log suggests changes for future versions of the program. 相似文献

This article first examines cultural limitations embedded in the Eurocentric Library of Congress Classification and calls for catalogers' sensitivity to authors' cultural background while cataloging the Bronze China archaeological materials. It then discusses the ambiguity in Library of Congress Subject Headings Manual H1225 and presents a debate on the necessity of including Chinese dynastic information in constructing subject headings through comparing facets extracted from this manual and title patterns of Chinese archaeological reports. Furthermore, this article elaborates the significance of the chronological issue from three different perspectives: Faceted Application of Subject Terminology headings, local library users' need, and next-generation catalogs. 相似文献

AGRICOLA (Agricultural Online Access), the bibliographic data base of the National Agricultural Library, is a computerized information retrieval system that can be adapted for use in many library functions. Although the system is most commonly used for retrieval of bibliographic references by subject, it can also be helpful in preorder and precataloging searches, in interlibrary loan verification, and in collection analysis. Various bibliometric studies that can be done with the on-line versions of AGRICOLA are described as well. 相似文献

The main criterion for selecting journals for indexing in Index Medicus, and thereby largely in MEDLARS, is quality. Subject scope varies with the voiced needs of the biomedical community. The Index aims to cover the best journals in all relevant subject fields, but the percentage of journals on a subject indexed depends on the quality of each journal. Country and language coverage depends on quality, even in the case of the best journals of each, although American biases may affect such selection. While a number of guidelines exist for identifying quality journals, information necessary to apply them confidently is often difficult to obtain. The National Library of Medicine is advised by an Ad Hoc Panel on the Selection of Journals for Index Medicus, composed both of NLM officers and extramural members. Criticism has been voiced that too many titles are indexed, compared with titles actually used, but no meaningful statistics of use exist which can identify titles which should be excluded from indexing. Continuing suggestions from users regarding titles indexed would benefit everyone. 相似文献

Sanford Berman 《Cataloging & classification quarterly》2017,55(6):347-360
In this interview, Sanford (“Sandy”) Berman discusses his career and his efforts to promote responsive, user-friendly cataloging practices over uncritical deference to prevailing standards. Topics covered include his work at Hennepin County Library, his thoughts on the campaign to change the subject heading “Illegal aliens,” his ongoing practice of proposing new Library of Congress Subject Headings, and his relationship with the Library of Congress. 相似文献
