In the late 1970s, Widener Library compiled a periodical price index from its own payment records, compared it with some published indexes, and, while significant differences in average prices were found, there was also a very strong correlation with the rate of price changes over the period 1967 to 1977. Using regression, Widener predicted its1977 average periodical prices with mixed results. This paper updates the Widener index with data, from 1978 to 1982, compares the Widener index to two published indexes, finds justification for continuing to compile its own index, and concludes that because Widener's average prices were predicted with good results for the last four years using a national index, it can reduce the staff's effort needed to produce the index by testing for accuracy once every five years. To be useful in budget preparation, this scheme is dependent upon the continued timely publication of the national index as well as adherence to the present local budget preparation schedule.
The following article outlines the basic steps in the identification and preparation of a wide variety of archival and library materials for microreproduction. No attempt has been made to introduce the reader to the language or technology of micro-film; that subject has been well covered elsewhere (an annotated bibliography is included for overview). Much of the information which follows is common sense in nature but perhaps for that reason is often casually applied or completely overlooked. The guidelines will mainly benefit the curator with no previous microfilming experience, but may also serve as a convenient checklist for the experienced processor or as a basis for development of a more detailed in-house manual. In each case, the goal is to eliminate unnecessary duplication of effort and to facilitate the production of more accurate and usable microforms.
There are machine-readable materials of various kinds that cannot be treated adequately under the rules of chapter 9 of the Anglo-American Cataloguing Rules, second edition. This article is concerned with the cataloging of materials known as floppy diskettes and used with Apple computers. In order to create temporary entries for the library of the Division of Library & Information Management at Emory University, the diskettes were analyzed in terms of each component of the bibliographic description, and comparisons were made between the existing rules and the materials in hand to see where they requiwrl modification. Suggestions emerged for different treatment of the Chief Source of Information, General Material Designation, Edition, Material Specific Details (not currently used at all for this type of material), Physiral Description, and Access Points. Permitting catalogers greater flexibility with machine-readable materials may help accommodate the multiplicity of products, rapidly changing technologies, and varying needs of users.
In contrast to the extensive discussion of the AACR2 provisions for bibliographic descriptions and for forms of headings, less attention has so far been given to its rule, for the choice of access points. A flowchart approach, developed by the authors for teaching purposes, is presented as a means of analyzing the decision logic for selecting main entries. Suggestions are offered for ameliorating some problems of ambiguity, apparent inconsistencies, omissions, unnecessary inclusions, definitions, and sequencing of rules.
The Washington Library Network online authority control system used for the COM catalog at Washington State University is an efficient tool for managing a research library catalog. The authority file maintenance work is accomplished through the cooperative effiorts of librarians in participating network libraries and the staff of the WLN Bibliographic Maintenance Unit. The link between the authority file and the bibliographic file facilitates catalog changes for network libraries.
Automatic acquisition of library materials in the form of approval plans and blanket orders is now widespread throughout American libraries with more than 80 percent of university libraries using these methods. The impact of such programs for European materials on collection development policies and acquisition procedures is discussed. European blanket order programs faced many problems in the latter half of the 1970s, with the result that many academic libraries began to fear they had lost control of these programs and decided to reevaluate their effectiveness. Some libraries, each as the Memorial Library at the University of Wisconsin-Madison, have canceled about half of their programs, while others, such as the University of Illinois at Urbana-Champaign Library, have revamped and expanded them. The specific problems of returns, exclusion of government and research institute publications, duplication of automatic acquisitions with firm orders, serial orders and publications with multinational imprints are addressed. The careful construction of subject profiles, review of materials, and the imposition of spending limits are designated as key means to gain control over automatic acquisition of European materials as well as to aid in collection development planning.
