Title

Telephone directories : alternatives to print

Abstract

Telephone directories are one of the most used sources of information in a reference collection. As the library literature indicates, they are a stable reference tool with a strong history of use. Further, it has been observed that telephone directories are familiar to most users, and resources such as the community pages and yellow pages are used extensively. However, the emergence of CD-ROM technology and libraries being charged for printed directories has raised questions concerning the future of an all-print telephone directory collection in libraries. Yet, evaluation of acquisitions alternatives for these resources is largely missing in the library literature. In this article, Boettcher and Kingma review the literature regarding the use of telephone directories in academic and public libraries and provide a cost analysis of the four purchasing options regarding telephone directories: printed directories, directory assistance, Phonefiche, and CD-ROMs
