The NLM current catalog

When the National Library of Medicine acquired a computer to augment its publication program, the intent was to present in one medium an index to journal articles and a catalog of books and new serial titles. The computer programs designed for indexing were unsatisfactory for cataloging, however; so two publications were issued, the Index Medicus and the NLM Current Catalog.The Current Catalog features separate name and subject sections, added volumes, and technical reports.The Express Cataloging Service was one of the first attempts to increase the speed and coverage of the Catalog. Shared cataloging with the Library of Congress, the Countway Library at Harvard, and the Upstate Medical Library in Syracuse, New York, have also contributed to the efforts toward improving this library service. An additional shared cataloging program, this time with the National Medical Audiovisual Center, is expected to be implemented shortly.

The Index Medicus: why it works and when it doesn't

A user study of the Index Medicus done at the Walter Reed Army Medical Center included responses from a group of sixty researchers, clinicians, residents, and interns. An analysis of the questionnaire shows that, while all respondents use the Index Medicus, most use it to search for a specific subject or a specific author reference. Comments received were critical of the delay from the time of journal publication until the appearance of its citation in Index Medicus. Suggestions were offered concerning the type of publication most of the respondents would prefer.     

A comparison of drug literature coverage by Index Medicus and Drug Literature Index

We compared Index Medicus and Drug Literature Index during a search concerning the toxicity of eight drugs used in treating tropical diseases. Indexes covering the years 1969, 1970, and 1971 were searched. Index Medicus produced 198 citations and Drug Literature Index 309. There were seventy citations that appeared in both indexes, a duplication of 16%. Highest percentage of duplication for any one drug was 38.9%. We concluded that Index Medicus and Drug Literature Index provide complementary coverage in the area of drug toxicity and that, therefore, both tools should be consulted in searches of this nature.

What the Index Medicus indexes, and why

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.     

TACOS:

TACOS is an acronym for TAble of COntents Service. It provides recipients with photocopies of the contents pages of journals selected from the hospital's list of serials. The service enables users to augment their journals by scanning additional tables of contents. TACOS coexists with and complements computer, SDI and other current awareness services. Growth over a five-year period is evident by an increased number of both TACOS requesters and TACOS journals requested. User satisfaction, as measured by a survey and willingness to pay, is high. TACOS is a simple, viable concept well worth implementing even in times of tight budgetary constraints.     

A CATLINE SDI for the reference department: collection development and current awareness tool

A method for using a CATLINE SDI (selected dissemination of information) as a current awareness and collection development tool for the health sciences reference department is described. This paper reports three years of experience with this service in an academic health sciences library. It emphasizes the exploitation of four data elements in the CATLINE file: the Abstracting and Indexing Tag (AI) Data Element; the Shelving Location (SL) Data Element; the MeSH Heading (MH) Data Element; the Subheading Qualifier (SH) Data Element.     

Subject indexing of the American Journal of Occupational Therapy in MEDLINE and NAHL.

Rehabilitation professionals need access to current journal literature for research and patient care. Using the American Journal of Occupational Therapy, subject headings from the MEDLINE and NAHL files are compared to determine coincidence and numbers of headings. Based on the study findings, an information retrieval plan is suggested that librarians may use in assisting rehabilitation personnel in effective use of Index Medicus, Cumulative Index to Nursing and Allied Health, and their online counter-parts.

Current Awareness from the User's Perspective: A Survey of Harvard Legal Academics

Abstract

This survey examines the basic needs of Harvard Law Faculty for information about new books and current journal articles. The purpose of this survey was to examine new media and technology in order to develop better current awareness tools, to better utilize the online catalog as a method of delivering current information to faculty, and to produce a new publication that fills in the gaps left by Current Index to Legal Periodicals and other sources. This survey looks at the production and circulation of photocopied pages of law reviews, recent acquisition lists, document delivery and interdisciplinary current awareness needs.     

Thesaural problems in an on-line system

This paper describes the construction of a synonym thesaurus or entry vocabulary for the SUNY Biomedical Communication Network, which will permit the user greater ease of access to the MeSH-indexed material without previously consulting a printed list of indexing terms. In order to discover the actual terminology used by a researcher, words were extracted from titles of articles appearing in Index Medicus, and compared with the subject heading under which they appeared. As well as strict synonyms, grammatical variants were also included. Work is continuing on relating other indexing vocabularies, such as Excerpta Medica and Current Medical Terminology, used in the biomedical world to MeSH terms.     

Editorial policy and the assessment of quality among medical journals

Many factors are weighed in judging the quality of a journal. Editorial policies in the instructions to authors section offer an important, though often neglected, source of information. In addition to directions on formatting and style, this section often includes financial disclosures and policies on coverage, peer review, confidentiality, human experimentation and duplicate submissions. This study analyzes the contents of instructions sections from several categories of medical journals to determine their usefulness in making collection development decisions. Included are journals currently considered the most prestigious, indexed in Index Medicus and Abridged Index Medicus, and not indexed in Index Medicus or subscribed to by a typical large academic health sciences library. It was found that in a statistically significant number of journals, the instructions to authors section is more likely to be included and substantive in highly regarded journals than in less prestigious journals. It is concluded that the amount of information in the instructions section is related to the quality of the journal and that these sections are a useful collection development tool.     

图书馆定题服务合同存在的问题及对策——兼论定题服务合同的性质、特征及履行原则

目前,定题服务合同内容普遍以格式条款进行表述,但存在着合同条款分散、条款内容不全面且不具体、权利义务不明确、部分条款内容对委托方不公平,合同履行缺乏有效协作,合同履行过程中有侵权行为等问题。故此,应明确定题服务合同属于技术服务合同,并应准确把握定题服务合同主体特定性、公益性、非营利性、持续性、格式性合同等特征,完善格式合同条款内容,严格遵守定题服务合同的履行原则。
