Book excerpt: Addresses the public library community's need for practical cost information related to Internet connectivity and services. It is not a "how-to" manual for connecting libraries to the Internet. The value of this study rests more with the development of cost models, worksheets, and cost categories that can assist public libraries to determine an appropriate type of Internet connectivity and service provision given the library's need. This study seeks to improve the knowledge base of information, not to offer a comprehensive treatment of the topic.
