Compared with bibliographies, library catalogs (whether in books, on cards, or online) have significant disadvantages from the user 's perspective. Bibliographies, however, unlike catalogs, provide no indication as to where the text itself may be found. The modern catalog can be seen as a response to the limitations of nineteenth-century library technology, which is no longer the technology of choice. A fundamental reconsideration of the relationships between bibliographies, records, and catalogs is overdue. The modern library catalog, fundamentally obsolescent in an online world, is in need of major redefinition.
Efforts to evaluate online public access catalogs should include a measure of how the catalogs affect the ability of libraries to make materials available and accessible to patrons. This study describes how availability analysis technique is used in implementing and evaluating an online catalog in the library of a small university. The performance measures are computed here to assist in setting realistic goals and in correcting catalog problems and to aid management in viewing the innovation in a broader context of library functions that contribute to, or hinder, patron success.
Establishing the boundaries for a survey of literature relevant to the work
of the Reproduction of Library Materials Section is no easy task. The common
interests between RLMS and the Preservation of Library Materials Section in
particular become especially evident as orle searches, and deciding what is
appropriate for the year's work in RLMS' areas of concern is often a puzzle.
Choices, therefore, are based on personal perceptions of what the members of
RLMS might find especially interesting. If my selections appear more than once,
it is better than not at all. If anyone's favorite piece is missing I apologize
and welcome a note about it so that it can be included in next year's survey.
A number of topics relating to the reproduction of library materials are considered, including microforms in libraries, bibliographic control, equipment, micro-publishing, preservation microfilming, the technical production of microforms, standards, photocopying, telefacsimile, copyright, and new technologies like digital image processing.
For the most part this survey is confined to materials published in 1987, together with a few items from 1986. It is unfortunate that 1986 lacks its own account of the year's work, but thanks to bibliographies prepared by Sinkule for micrographics (151), Fischer for optical and videodisc technology (66), and Swora for optical digital scanning and storage technology (155), the hiatus is less of a problem than it might have been. And for 1987 my special thanks are due to Lois Carrier, University of British Columbia Library: Jack Pontius, Pennsylvania State University Library, and Tamara Swora, Library of Congress for all their help in tracking down possibilities for inclusion.
Subject access literature published in English-language journal articles and monographs in 1987 is the focus of this review. Two areas reported in 1986, i.e., the availability of the machine-readable Library of Congress Subject Headings (LCSH-mr) and research on incorporating the Dewey Decimal Classification (DDC) into the subject searching capabilities of online bibliographic systems, set the stage for additional and related work in 1987, particularly on multiple thesauri, subject authority control through LCSH-mr, and the usefulness of machine-readable classifications in online bibliographic systems.
The terms library science and information science (and, indeed, many other "sciences") are used rather casually. The scientific approach attempts to establish general laws covering the behavior of events or objects and to recognize a pattern among separate items of information that can be used to predict future events. Scientific research involves the controlled investigation of these relations. It is aimed at the establishment of theory , a set of general concepts to explain the relationships among variables. A selective approach is taken here to the reporting of the re-search in technical services published in 1987, based on the research methodology used. Studies where methodology is not clearly defined and discussed have been deliberately excluded.
This article describes the application of the Dewey Decimal Classification "phoenix" for data processing, computer science, and computer engineering (004-006) to a selection of materials classified according to older schedules in a Boston-area public library. The revised schedules were easy to learn and to apply, even for the novice user, and the browsability of the set of materials in the study was improved through reclassification.
The problem resolution phase of a retrospective conversion project for monographic records at the University of Massachusetts-Amherst is examined. Knowledge needed by the problem-solving librarian is discussed, and the kinds of problems encountered are categorized and described. Difficulties involved in standardizing the editing process for problem records are noted, and suggestions for developing editing guidelines are offered.
Although policies governing the operation of circulation control vary from
library to library, purposes, needs, operational goals, procedures, and staffing
pat-terns remain similar. In recent years, modern technology has had an impact
on work flow and procedures of the operation, but not to an extent where national
standards were called for.
Despite the importance of circulation control, patrons, staff and library administrations tend to perceive this as a routine operation because it has been a relatively mechanical, though integral, part of the library's overall operation for so many years. Even its efficiencies or inefficiencies are perceived to be routines. Although the need for it was never questioned and nothing indicates it will be challenged in the near future, circulation control has maintained a low profile among various library functions. This prevailing image may be the reason a periodic literature survey on circulation control has not been popular.
According to the Automation Inventory of Research Libraries (ARL/OMS 1987), of 113 libraries responding to the survey, 106 libraries were impelementing, modifying, or planning for an automated circulation system. The majority chose a mechanism to link physical access to bibliographic access points. This requires comprehensive analyses of circulation functions in a broader context, including technical services and collection development. To cope with aging resources, traditional circulation policies may be challenged. How? Nontraditional resources such as online publications are gradually but surely increasing. Will the present concept of circulation apply to new types of publications? These questions motivated this brief survey of circulation control literature.
