A Study of Performance of Five Book Dealers Used by Louisiana State University Library

Sandra L. Stokley and Marion T. Reid

A study was conducted by the Order Department of the Louisiana State University Library to measure the performance of five domestic book dealers during the 1975-76 fiscal year. The data were obtained through a detailed analysis of 400 purchase orders from each of the five dealers. The results showed that certain dealers do give greater discounts and have shorter turn-around times than others, but these services must be weighed against problems encountered. These results have been used by Order Department personnel in determining which book dealer to use in a given situation.

The Principle of Uniform Heading in Library of Congress Subject Headings

Lois Mai Chan

The recent policy of the Library of Congress to adopt split files and its increasing use of duplicate entries represent a relaxation of the principle of uniform heading that has been a major principle in Library of Congress Subject Headings since the beginning of the dictionary catalog. Split files entail the use of a new heading for an existing subject while maintaining a separate file for entries already cataloged under the old heading without recataloging. In order to understand the ramification and implications of this recent development, a discussion of the origin, rationale, and application of the principle of uniform heading seems to be appropriate.

The Adequacy of Library of Congress Subject Headings for Black Literature Resources

Doris Hargrett Clack

Subject analysis for black literature resources is a neglected area in research. This initial investigation of Library of Congress subject headings assigned to black literature resources is concerned with determining the adequacy of subject analysis of these materials in terms of specificity of headings. The extent to which these subject headings are coextensive with the subject treated in the works is a determining factor in the ease or difficulty experienced in subject catalog searches and is thus examined. The question of adequacy is explored. The study concludes with a description of prescriptive measures necessary for the resolution of the problem identified.

Punctuation in Library of Congress Subject Headings

Hilda Steinweg

An analysis of the punctuation of the subject headings presented in the eighth edition of Library of Congress Subject Headings reveals that the punctuation marks most often used are the comma, parentheses, and hyphen. Examples of their various uses are presented and discussed.

A Rationale for the Use of Split Files for Subject Headings

Pamela Walker

Based on the assertion that the point of view of subject headings should be descriptive rather than prescriptive, a logical rationale for split files for subject headings is presented. It is asserted that the use of split files will help to resolve some of the controversies relating to headings for races and other groups of persons.

Poland Is Not Yet Defeated, or: Should Catalogers Rewrite History? With a Discourse on When Is an Island Not an Island?

Han H. Wellisch

The revised instructions of the Library of Congress on indirect subdivision of topical headings are analyzed from the points of view of the feasibility of the instructions, their cost-effectiveness, and their usefulness for users interested in historical and/or geographical aspects of a topic. It is asserted that the new practices will lead to subject headings that are incongruous and unpredictable for users not familiar with the decisions made by LC catalogers. It is proposed instead to use direct subdivision of topical headings for all countries or regions in keeping with previous LC practice for cities, counties, and regions in the United States.

Conference Publications: Serials or Monographs?

Jim E. Cole

The publications of conferences may be handled either as serials or monographs. There are at present no definitive guidelines for their treatment. After considering the problem, the author favors treatment as monographs.

An Adapted Library of Congress Classification for Children's Materials

John W. Perkins

After the Inglewood (California) Public Library had converted its adult subject collection to the Library of Congress Classification, it developed an adapted LC classification for children's library materials. The new system uses a two-letter classification, followed by one or two numbers when more detail is required. The system has been in use for more than five years and has received a gratifying response from children's librarians. Materials are readily located, class numbers are easy to remember, and the adaptation prepares children for a transition to the use of adult LC.

Multiscript and Multilingual Bibliographic Control: Alternatives to Romanization

Hans H. Wellisch

In response to C. Sumner Spalding's plea for alternatives to the practice of Romanization, the implications of separation of catalogs by script and the sep¬aration of entries in non-Roman scripts by language are explored. Data on present book production show that no more than ten scripts produce practically all modern books, the six most productive being Roman, Cyrillic, Japanese, Chinese, Devanagari, and Arabic. Most libraries have extensive collections of books in only a few of the non-Roman scripts. The filing of non-Roman entries in separate parts of a catalog, the specific problems of smaller collections lacking language experts, and the difficulties posed try logographic scripts are also considered. It is proposed to establish separate machine-readable data bases for each script and to produce the National Union Catalog in corresponding separate "registers," possibly in microform. True universal bibliographic control can only be achieved if direct access to materials, irrespective of script, is provided in library catalogs and bibliographies.

Recommended Data Elements for the Descriptive Cataloging of Computer-based Educational Materials in the Health Sciences

Becky Lyon-Hartmann and Charles M. Goldstein

A large part of the mission of the National Library of Medicine is to collect, index, and disseminate the world's biomedical literature. Until recently, this related only to serial and monographic material, but as new forms of information appear, responsibility for bibliographic control of these also must be assumed by the National Library of Medicine. This paper briefly describes the type of information that will be necessary before descriptive cataloging of computer-based educational materials can be attempted.
