The Validity of Book Price Indexes for Budgetary Projections

H. William Axford

A comparison of the average prices paid for books received through approval plans and the average prices listed annually in the Bowker Annual is reported. The results strongly indicate that the average price paid per title through approval plans is a more reliable guide for budgetary projections than the average price per volume or title listed in the trade sources.

Book Selection Tools for Subject Specialists in a Large Research Library: An Analysis

Geza A. Kosa

In a large research library that relies mainly on title-by-title selection, 3,522 order slips were analyzed in order to determine the relative usefulness to subject specialists of various selection aids. The analysis shows that each specialist checked an average of about thirty selection aids, although almost three-fourths of the orders were selected from only six tools. The two most useful types of sources for selection were bibliographies and publishers' advertisements.

Effect of Uneven Card Distribution on a Card Catalog

Abraham Boorstein

Although the catalog is one of the most important instruments in a library, little effort has gone into analyzing its managerial problems. Among these problems are those relating to the catalog's growth and eventual expansion. This paper presents a simple model of catalog growth that allows one to estimate how many drawers will overflow in a period of time. A conclusion drawn from this analysis is that when cards are redistributed, every effort should be made to ensure an even distribution of cards.

Subject Headings for a Local Catalog

H. Anthony Rydings

The University of Hong Kong Library is compiling a union catalog of materials relating to Hong Kong available in local libraries. The main sequence is an alphabetical subject catalog, using modified Library of Congress (LC) subject headings, with author and title indexes in Western languages and Chinese. This article describes methods adopted to modify LC headings to indicate relationship of materials to Hong Kong. Examples are given of special form, subject, and geographical headings, and of the problem of Chinese names. Double entries under generic and specific headings have frequently been used; the value of this approach has still to be tested by usage.

A Classification Scheme for Publications of Intergovernmental Organizations

Walter L. Newsome

A classification scheme for international, intergovernmental organizations in use in the University of Virginia's main library is described briefly. The need for such a scheme arose when the library decided to centralize intergovernmental organization documents in its public documents section. The system utilizes an acronym and type of publication scheme developed by combining some of the principles of the Superintendent of Documents and the United Nations series symbols systems.

Melba Davis Adams

The application of the Dewey Decimal Classification and its place in the subject analysis procedures followed by the British National Bibliography is described as observed by an exchangee from the Decimal Classification Division of the Library of Congress.

Application of the Dewey Decimal Classification at the Library of Congress

Robert Rosstrotter

The application of the Dewey Decimal Classification at the Library of Congress and the editorial procedure carried out in preparing a new edition of the classification are described by the head of the Dewey Section of the British National Bibliography. Classifiers in the Decimal Classification Division have only a shelf list to guide them in placing like books together. On the other hand, they can read between the lines of the classification by means of access to the minds of the editors. The editors themselves must walk a tightrope between the changing demands of knowledge and the need to preserve continuity.

The Phoenix Schedule 510 in Dewey 18

Barbara K. Schaefer

Claims that the 510 schedule of the Dewey Decimal Classification has been completely revised in the eighteenth edition and now reflects modern mathematical concepts, based on literary warrant, are tested by: (1) comparing Dewey 18 and Dewey 17, and (2) comparing Dewey 18 and the classification scheme of the American Mathematical Society. Dewey 18 is found to be an improvement over Dewey 17, both in content and structure, but it still is inadequate for classifying contemporary mathematical literature.

Classifying Law Materials Using the Library of Congress Classification

Suzanne Tipler

The unfinished K schedule for Law presents a challenge to libraries committed to the use of the Library of Congress classification. This article suggests guidelines for the classification of law materials in a small library using the published parts of the scheme and some extrapolations from them.
