This document proposes a model of the decision making process required of research libraries when they embark on digital conversion projects. A series of questions are offered that focus on facilitating the decision making process for library managers. Questions of what and how to digitize are placed in the larger framework of collection building by focusing, first on the nature of the collections and their use, and second, on the realities of the institutional context in which these decisions are made. This booklet is divided into 10 main sections: (1) Introduction; (2) Copyright: The Place To Begin; (3) The Intellectual Nature of the Source Materials; (4) Current and Potential Users; (5) Actual and Anticipated Nature of Use; (6) The Format and Nature of the Digital Product; (7) Describing, Delivering, and Retaining the Digital Product; (8) Relationships to Other Digital Efforts; (9) Costs and Benefits; and (10) Conclusion. "Selection for Digitizing: A Decision-Making Matrix" is also included on the back cover. (AEF)
