Collection Development, Collection Management, and Preservation

Dan C. Hazen

Preservation is one of the urgent issues of contemporary librarianship. Thus far relativey little has been written on decision making for preservation. This article first delineates the types of decisions implied by preservation activity and then suggests structures and criteria for each. The consideration most relevant to decision-making structures appears to be the scale of activity, and criteria analogous to those for collection management and collection development are suggested for the two main types of decision. The article highlights also the information gaps that limit our current ability to make intelligent preservation decisions.

AACR2, OCLC, and the Card Catalog in the Medium-Sized Library

John Hostage

The impact of AACR2 on the card catalog in a medium-sized library was analyzed in a study using a random sample from a year's cataloging. Rates of conflict, amount of corrections, and creation of split files were considered under different scenarios.

Bibliographic Structure Possibility Set: A Quantitative Approach for Identifying Users' Bibliographic Information Needs

Josefa B. Abrera

The principal objective of this study is to determine the bibliographic control requirements of a small to medium-sized public library from the point of view of the expressed needs of the library patron through telephone and catalog reference. Bibliographic elements in addition to author, title, and subject are identified. All elements are measured as to the extent and use of each far retrieval. The results of the study of users' requests and the nature of their bibliographic structure indicated that present bibliographic data in a catalog record provide sufficient information to support users' needs and that there is no immediate need for expanding access beyond the present levels provided in a library catalog.

Core Collection Development in a Medium-Sized Public Library

Carolyn Moore

This paper reports on a procedure built on the research of Trueswell and McGrath and based on the analysis of shelf and circulation samples of fiction and nonfiction according to subject, last circulation date, and publication date and supported by a user questionnaire. Two null hypotheses are considered: (1) When the 80/20 rule is tested, there will be no difference between fiction and nonfiction; (2) restructuring through weeding and adding will have no effect on the circulation to holdings ratio. To date, experience with the procedure at the Clearwater Public Library indicates that bath hypotheses are false. The core collection in the public library is much larger than those reported by Trueswell, but fiction seems to have a somewhat smaller core than nonfiction. Restructuring has had little effect on low use sections of the nonfiction collection. Implications in public libraries are for priorities in the selection of areas of the collection for development and/or weeding.

Variant Edition Cataloging on OCLC: Input or Adapt?

Douglas A. Cargille

The question of whether to input a new record or to adapt an existing record when cataloging variant editions is addressed. In the OCLC environment, arguments from the standpoint of both economy and interlibrary loan service appear to favor the use of the NEW command for the input of a new record.
