A weighted system measured the frequency with which individual MARC fields provided matches for the keywords. The results of this study lead to recommendations for maximizing search strategies. This paper theoretically models and econometrically tests the determinants of third-degree price discrimination concerning institutional versus individual pricing by the publishers for the top 99 journals in economics. Unstandardized and standardized coeffiient estimates from probit and least-squares regression methods are derived across each measure of price discrimination. Policy recommendations are offered given empirical findings for libraries as to how to limit the negative consequences of price discrimination practiced by publishers.
Emphasis is on classification codes as access points in searches on mathematical topics.
An exploratory study was conducted which serves as a framework for tracing indications of the problem from indexing through retrieval. The study postulates that users may identify LC numbers on desired mathematical topics through an OPAC search. Discussion follows on how the problem of level of specificity in multifile OPAC searching might be alleviated. The main, recurrent questions at information desks in the Library concern periodicals. In an effort to adress this need in a new way, the Library decided to create a periodicals information center for self-help instruction, and to develop a tutorial in HyperCard on how to search for information in indexes and find periodicals in libraries.
