A survey of present uses and arrangement of medical library card catalogs was made in order to determine current practices and trends. Attention was focused on the influences of MeSH on the card catalog. The results indicate that the prevalent type of card catalog found in medical libraries is the divided catalog. In addition, it appears that this catalog arrangement is gaining acceptance, and the trend is toward division. MeSH has an effect on the organization of the card catalog; libraries indicate that it is an influential factor in the decision to divide the catalog. 相似文献

Conversion to MeSH and other reasons are enumerated for the division of an undivided dictionary card catalog into a three-way divided catalog, consisting of Proper Names, Titles, and Topical Subjects sections. Methodology of division is described. Conversion from Library of Congress Subject Headings to Medical Subject Headings (MeSH) as an authority list stimulated such concurrent changes as (1) the introduction of a guide card system that eliminates typing of subject headings on catalog cards and (2) the adoption of a filing system that employs reverse chronological order for all types of sequential material in the Proper Names and Titles sections and for all material in the Topical Subjects section. The ancillary decisions, procedures, and methods necessitated by these major conversions are also described. 相似文献

Library of Congress subject headings (LCSHs) are generally felt to be especially inadequate in dealing with social science materials. I attempted to see whether PRECIS indexing "brought out" what a group of urban studies works were "about" better than LC subject cataloging. PRECIS does turn out to provide more access points than LCHS; but this advantage would disappear in an on-line catalog having key-word access. PRECIS also ends up providing apt headings more of the time than LCSH; its advantage here, however, would diminish if LCSH (1) employed more up-to-date vocabulary and (2) included a time facet more freely. Neither LCSH nor PRECIS turns out to be particularly successful in dealing with "multi-tiered works," those whose "intellectual subject(s)" differ from their "ostensible subject(s)." I argue that the best way to provide good subject access to these (as well as many other kinds of) works would involve supplementing traditional subject headings with abstracts or summaries. 相似文献

In the Dewey Decimal Classification (DDC) Online Project, subject searching and browsing of DDC Schedules and Relative Index were featured in an experimental online catalog. The effectiveness of this DDC in an online catalog was tested in online retrieval experiments at four participating libraries. These experiments provided data for analyses of subject searchers' use of a library classification in the information retrieval environment of an online catalog. Recommendations were provided for the enhancement of bibliographic records, online catalogs, and online cataloging systems with a library classification. In this paper, subject searchers' use of the subject outline search capability of the experimental online catalog is described. This capability was unique to the experimental online catalog and all other online catalogs, because it referred searchers to online displays of the classification schedules based on their entry of subject terms. Failure analyses of subject outline searches demonstrated its specific strengths and weaknesses. Users' postsearch interview comments highlighted their experiences and their satisfaction with this search. Based on the failure analyses and users' interview comments, recommendations are provided for the improvement of the subject outline search in online catalogs. 相似文献

Lower DVD costs and increased patron demand have led to more video recordings in library catalogs. With long lists of cast and crew, these catalog records are more detailed than many books. For institutions requiring authorized name headings, both personal and corporate, heavily detailed catalog records for video recordings can be burdensome. Not all libraries that contribute original cataloging records to utilities such as OCLC are authorized to create corresponding authority records. A recent survey asked a sample of catalog librarians of video recordings in different types of libraries about their viewpoints and workflows in the context of authority control. 相似文献

Wayne State University Medical Library (WSUML) revised its monograph subject catalog in 1961 utilizing the 1960 edition of MeSH as an authority list. With the introduction of MEDLARS in 1963 by NLM, all topical subheadings were omitted from MeSH. Inasmuch as this omission could not accommodate the needs of WSUML, the 1960 edition of MeSH was retained as a guideline.In January 1966, when MeSH resumed the incorporation of topical subheadings, WSUML was faced with a decision whether to continue the current policy or to adopt the form as presented in the latest edition of MeSH. This report describes the methodology employed in adopting a new policy, the findings which resulted from the change, and an evaluation of this reorganization. 相似文献

Prior to planning for implementing the NOTIS system, the Vanderbilt Medical Center Library had not fully cataloged its government publications, and records for these materials were not in machine-readable format. A decision was made that patrons should need to look in only one place for all library materials, including the Health and Human Services Department publications received each year from the central library's Government Documents Unit. Beginning in 1985, these publications were added to the library's database, and the entire 7,200-piece collection is now in the online catalog. Working with these publications has taught the library much about the advantages and disadvantages of cataloging government documents in an online environment. It was found that OCLC cataloging copy is eventually available for most titles, although only about 10% of the records have MeSH headings. Staff time is the major expenditure; problems are caused by documents' irregular nature, frequent format changes, and difficult authority work. Since their addition to the online catalog, documents are used more and the library has better control. 相似文献

For years, Library of Congress (LC) subject headings have been criticized for not keeping up with the times. This has never been so much in evidence as at present, when so many countries have been going through a state of flux. There has seemed to be a stubborness on the part of LC to change ethnic and racial, as well as sexual and medical headings. While it is well and good not to jump to conclusions and change everything in sigh, delaying change can frustrate users of today's online and card catalogs. After bringing readers up-to-date on the changes that have occurred over the last 20-some years, I will show how your own library's catalog can be updated, or at least rendered more useful to your patrons. In doing so, it is seen that automation can enhance, as well as prevent, subject heading updating. 相似文献

Perhaps the greatest power of folksonomies, especially when set against controlled vocabularies like the Library of Congress Subject Headings, lies in their capacity to empower user communities to name their own resources in their own terms. This article analyzes the potential and limitations of both folksonomies and controlled vocabularies for transgender materials by analyzing the subject headings in WorldCat records and the user-generated tags in LibraryThing for books with transgender themes. A close examination of the subject headings and tags for twenty books on transgender topics reveals a disconnect between the language used by people who own these books and the terms authorized by the Library of Congress and assigned by catalogers to describe and organize transgender-themed books. The terms most commonly assigned by users are far less common or non-existent in WorldCat. The folksonomies also provide spaces for a multiplicity of representations, including a range of gender expressions, whereas these entities are often absent from Library of Congress Subject Headings and WorldCat. While folksonomies are democratic and respond quickly to shifts and expansions of categories, they lack control and may inhibit findability of resources. Neither tags nor subject headings are perfect systems by themselves, but they may complement each other well in library catalogs. Bringing users’ voices into catalogs through the addition of tags might greatly enhance organization, representation, and retrieval of transgender-themed materials. 相似文献

The name main-entry heading has been a source of controversy throughout the history of Anglo-American cataloging with debate being closely tied to author identification. It is not surprising that debate has gained momentum as the functionality of online library catalogs and the costs of cataloging are under increasing close scrutiny. Following an historical overview of the name or author main-entry heading, this article discusses the finding and identifying functions of online catalogs as they relate to authorship. The article concludes that the name main-entry heading is an essential component of online catalog citation displays through which catalog users decide the usefulness of retrieved cataloging records. 相似文献

The purpose of this study was to determine the amount of correlation between National Library of Medicine classification numbers and MeSH headings in a body of cataloging which had already been done and then to find out which of two alternative methods of utilizing the correlation would be best.There was a correlation of 44.5% between classification numbers and subject headings in the data base studied, cataloging data covering 8,137 books. The results indicate that a subject heading index showing classification numbers would be the preferred method of utilization, because it would be more accurate than the alternative considered, an arrangement by classification numbers which would be consulted to obtain subject headings. 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

Applications of informatics in veterinary medicine 总被引：3，自引：0，他引：3
This study used the peer-reviewed biomedical literature to define the veterinary informatics knowledgebase and associated subspecialties, and assesses the level of activity in the field over the thirty-year period from 1966 through 1995. Grateful Med was used to search the MEDLINE bibliographic database for articles that shared one or more Medical Subject Headings (MeSH) keywords from the veterinary and medical informatics subject headings. Each of ninety-five MeSH medical informatics terms was assigned to one of twelve veterinary informatics subspecialties. The number of articles retrieved by each MeSH keyword and subspecialty was calculated. A total of 611 articles were retrieved, representing the contributions of 1,338 authors published in 153 journals. The field experienced slow growth over the twenty-year period from 1966 through 1985. In the following decade, the cumulative number of veterinary informatics articles almost tripled and the percentage of veterinary-related articles that included an informatics component increased almost two-and-one-half fold. Despite this recent growth, the number of veterinary-related articles with an informatics component has never exceeded 1% of either the veterinary or medical informatics literature over the past thirty years, and representation of veterinary subspecialties in the literature varied widely. 相似文献
