Sources for Determining Citation Practice for Court Reports throughout the World

Phyllis C. Marion

This bibliographic essay points out major differences in court reporting and citation practices and suggests reference tools to assist in ascertaining the accepted citation practice in a country.

A Comparison of Library Tools for Monograph Verification

Elizabeth H. Groot

Six commonly used library tools were compared as to their effectiveness for verification of monographs before acquisition. The tools compared were the following: American Book Publishing Record, Books in Print, Cumulative Book Index. Micrographic Catalog Retrieval Systems, National Union Catalog, and the OCLC online service. Although costly, the OCLC online service took the least time to use and gave the highest retrieval percentages. Surprisingly, during the imprint year of the monographs, the inexpensive Books in Print gave retrieval percentages equal to OCLC. A cornputer program written in BASIC, was used to calculate the retrieval percentages for all possible combinations of the reference tools, over three periods of time. A cost-analysis method was developed that will permit a library of any size to determine which of the reference tools will be best for its purposes.

An Evaluation of an Oregon School District's Centralized Ordering and Processing System

Leslie Hendrickson and Marie Celestre

This evaluation of a medium-sized school district's centralized ordering and processing system was undertaken to investigate complaints about time lags in the operation of the system. Data were collected through interviews, questionnaires, and a random sample search of ordering and processing records. The authors discovered a pattern of time lags at each stage of the operation. There are indications these delays are no longer than those in the earlier decentralized system.

The King Research Project: Design for a Library Catalog Cost Model

Angela G. Mullikin

The Association of Research Libraries sponsored the development of a binary catalog cost model by King Research, Inc. over a period of several months in 1979. The seventy-two participating libraries considered alternate forms of catalogs, including various combinations of card, COM, and online, in unified or split forms and prepared input data for computer runs to arrive at costs. Although definite conclusion were impossible because of many variables, card catalogs appear to be less costly than other forms. It is possible that results might be different if costs were spread over a ten-year period instead of the five years used in the model.

The Effect of Closed Catalogs on Public Access

James R. Dwyer

Microcatalog use studies conducted at the University of Oregon have demonstrated that users encounter difficulties with multiple-file microfiche catalogs. This research supports theories by Mooers and others which suggest that closed catalogs with supplements will not be fully understood or utilized by the public. The University of Oregon survey results are compared to other studies which indicate that the problem is multiple lookups, not catalog format. Retrospective conversion strategies and the costs of converting records into machine-readable form are considered.

Language of the Library of Congress Subject Headings Pertaining to Society

Jan Wepsiec

Existing headings are grouped into twenty-two types, using the syntactic structure of the modifier of the focal noun as the criterion of differentiation. Some semantic types are found to have been expressed by more than one syntactic type. Reasons are given for eliminating certain syntactic types, reducing the total from twenty-two to fifteen without loss of specificity of the headings.

The Concise AACR2

Frances Hinton

The Concise AACR2: Being a Rewritten and Simplified Version of Anglo-American Cataloguing Rules, Second Edition, by Michael Gorman, is scheduled for publication in North America by the American Library Association and the Canadian Library Association, and in Great Britain by the Library Association. As its title indicates, The Concise AACR2 is not an abridged edition. Instead, it presents the essence and basic priniciples of the second edition of the Anglo-American Cataloguing Rules for the use of small general libraries and for teachers of general cataloging courses. Because it is designed for small libraries, it omits specific rules for describing materials unlikely to be included in their collections, such as machine-readable data files. It also omits many of the more complex rules for choice of entry and form of heading on the theory that small libraries acquire primarily current, book-trade publications by authors with conventional names, for which the general rules will provide satisfactory access points.
