A model is needed to depict how individual selection decisions are made. This paper presents such a model based upon a typology of contexts according to which citations (in the sense of references) are understood and used for selection. Three contexts are defined. the "syntagmatic context "within the citation itself the "contexts of supplementation" provided by the selection source, and the "contexts of resolution" derived from the selector's experience of the collection, the clientele, and the subject.
Giving a single wholesaler virtually all of the Knox College Library's firm orders, in return for promises of better delivery and discount, necessitated a change in the method of evaluating wholesaler performance. Unable to compare our vendor with his competitors, we instead attempted to profile the vendor's performance, coding the firm orders by response time in weeks and then arranging them by accounts (or subject areas) and by publishers. This method allowed us to identify specific strengths and weaknesses in our vendor's stock and to determine how well he could serve the particular needs of the library. About thirty-six hundred orders in twenty-nine accounts (or subject areas) and forty trade and academic publishers were analyzed, with the results indicating that, despite the vendor's claims for the comprehensiveness of his stock, in fact, only 40 to 50 percent of our orders could be filled from his stock, and, furthermore, his performance with regard to both subjects and publishers varied as much as 50 percent The findings suggest that order periods should be shortened from twenty or twenty-four weeks to sixteen or twelve weeks to encourage delivery and that a vendor's performances with specific subjects and publishers should be considered before placing orders.
To provide adequate library resources for its various campuses in the changing financial climate of the last decade, the University of California has taken steps to establish an adequate base book budget and to measure price increase needs to maintain budgeted acquisition rates. These steps were taken within the context of the University of California library development plan, which had been adopted in 1977 with the twin goals of reducing the rapid rise in library costs and improving library service. To achieve these goals, the plan recommended as its main objective increased cooperation among the libraries of the university and the creation of a library system that would serve all university library users, regardless of campus or location. This paper will concentrate on that portion of the plan that resulted in book budget increases and a balanced budget acquisition rate among the campuses.
A cost model is presented for use by librarians desiring to investigate various alternatives for accomplishing retrospective conversion. Advice on taking a random sample and gathering information is given, and the steps necessary to cost the project are set out. A hypothetical example using two alternative methods is provided.
J. Kaiser (1868-1927) developed a system of subject indexing based on what he called "concretes" and "processes" to govern the form cf subject headings and subdivisions. Although Kaiser applied his systematic indexing to specialized technical and business collections, his ideas are entirely applicable to all book collections and catalogs. Though largely ignored, Kaiser 's system is of permanent interest in the study of the development of subject analysis.
This study has attempted to determine the influence a card catalog has on circulation in a small public library. One hundred ninety-eight books were selected randomly from the nonjuvenile collection and circulation of each title for a fourteen-week period was ascertained. The books were then divided into two groups. Group A, the experimental group, had all related catalog entries withdrawn from the card catalog, while the cards for Group B, the control group, were left intact. The removal of the cards had no statistically significant influence on circulation.
