Cataloging Nonbook Materials: Mountain or Molehill?

Suzanne Massonneau

The development of cataloging codes for non book materials is surveyed, with particular attention devoted to the absence of stated objectives, the problem of the integrated catalog, terminology, and examples, and some of the complications caused by the blanket use of title main entry.

The Standardization of Cataloging Rules for Nonbook Materials: A Progress Report-April 1972

Jean Riddle Weihs

A brief history of the development toward standardization of rules governing the cataloging of nonbook materials is given. The two remaining unresolved issues -- terminology and main entry -- are discussed and the various points of view concerning these issues are presented. This article was written in April 1972. By the time it is published, positions may well have shifted or changed altogether.

The Plain "J": A Documents Classification System

Mina Pease

This paper explains a numbering scheme for the processing of government documents, especially those housed in a documents collection. The proposal is based on the idea that a uniform standard numbering scheme is one of the necessary elements in the functioning of a large research documents collection. This scheme is a modification of the Library of Congress "J" class. The number assigned in the "J" class to the official publications of a governmental body is expanded to be used for all publications of that government. Further, the "J" schedule is enlarged to J four and J five digits so that publications of local governmental bodies and of international governmental organization can be included in the scheme.

Toward Some Standards for the Library Card Catalog Tray

Allan Boudreau and Donald J. Yucht

Commercial card catalog tray tests are unrelated to actual in-use wear. Specifications for card catalog trays for the new Elmer Holmes Bobst Library at New York University, detailed in this article, are designed to meet the most demanding of actual needs.

Applying the Principle of Dealing With Exceptions

J. McRee Elrod

Traditional library methods assume that each entry going into the catalog must be verified for correctness and relation to the local catalog. Some would make cataloging with Library of Congress copy a purely clerical function, using entries as received. Advocated here is a method for identifying exceptions -- those main, added, and subject entries which are incorrect -- and for dealing with them. Much of the quality obtained by verifying each entry can be retained even when this step is abandoned in the interest of speed, when check points are established to catch divergent headings as they enter the catalog.

An Integrated, User-Oriented System for the Documentation and Control of Machine-Readable Data Files

John D. Byrum, Jr. and Judith Rowe

The purpose of this paper is to offer a solution to the problems of documentation and bibliographic control of machine-readable data files. It is a solution which attempts to meet both the needs of the data user and the data librarian. It is designed to make readily feasible the conversion completely or in part to a computer-based operation and to tie in directly to an information retrieval system in the future. The four elements of this documentation and control system are: standard catalogue entries, data abstract or data description forms, content documentation codebooks, and records of physical and logical characteristics of the data set.

Comparative Card Production Methods

Ann Craig Turner

The method of catalog card production chosen by a library relates directly to the annual volume of its card production. Seven methods of card production tried by the University of British Columbia Library are described and compared in terms of total cost per set of cards and their applicability to libraries of various sizes. Tables list separately labor, supplies, and equipment costs for the various methods, and the information includes timings for each operation as performed by a stated level of library staff. The conclusion emphasizes the need for libraries to share data about card production methods that they have tried.

The Schedule of Main Subjects Proposed for Edition 7 of the Colon Classification

P. Jayarajan

In Edition 7 of Colon Classification (CC) ninety-nine new Main Subjects -- including Partial Comprehensions -- have been provided in its Schedule of Main Subjects. These are of the following five kinds: (I) Distilled Main Subjects, (2) Partial Comprehensions, (3) Fused Main Subjects, (4) Promoted Main Subjects, and (5) Truly new Main Subjects. But, none of these new Main Subjects has caused any change either in name or in the relative sequence of the forty-two Main Subjects in Edition 6 of CC.

Reading List in Classification Theory

Phyllis A. Richmond

Introductory reading list covering most of the areas of modern classification theory. Includes definitions, bibliographic and nonbibliographic classification, recent views on classification, subjects related to classification, and miscellaneous background material such as scientific method, logic, statistical methods, etc.

Dewey 18: Another Step in an Evolutionary Process

Lois Mai Chan

In Edition 18, the editors of DDC again tried to steer a middle course between "the integrity of numbers" and "keeping pace with new knowledge." An effort was made to keep the changes to a minimum yet without overly compromising the updating of the system. However, all the changes made were not caused by new knowledge. Many of them were made for structural reasons, i.e., in an effort to rectify irregularities which had developed in the scheme over the years. Two basic factors of the system, namely, classification by discipline and notational constrictions, have affected the nature and the form of many of the changes.
