Title

Choosing among the options for patron access databases : print, online, CD-ROM, or locally mounted

Source

Reference librarian. 1993, no.39, S.85-97

Abstract

The proliferation of electronic information sources has added new dimensions to building library reference collections. As reference librarians select titles for their collections, they must also choose the most appropriate medium. For some information the choices include print, microforms, CD-ROM databases, online hosts, or locally mounted databases. Factors involved in the selection of the appropriate medium include database costs, licensing agreements, hardware/software requirements, retrieval modes, system capabilities and information transfer. Integrating the new services into existing structures so that library users can derive the maximum benefit from the availability of the databases is a primary concern
