ZIDAR opined that the software one purchases was more important than the hardware and might also cost more than the hardware, but it was likely to prove critical to the success or failure of one's system. In addition to a stand-alone scanning workstation for image capture, then, text capture requires one or two editing stations networked to this scanning station to perform editing. Editing the text takes two or three times as long as capturing the images. Finally, ZIDAR stressed the importance of buying an open system that allows for more than one vendor, complies with standards, and can be upgraded. ****** +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ WATERS *Yale University Library's master plan to convert microfilm to digital imagery (POB) * The place of electronic tools in the library of the future * The uses of images and an image library * Primary input from preservation microfilm * Features distinguishing POB from CXP and key hypotheses guiding POB * Use of vendor selection process to facilitate organizational work * Criteria for selecting vendor * Finalists and results of process for Yale * Key factor distinguishing vendors * Components, design principles, and some estimated costs of POB * Role of preservation materials in developing imaging market * Factors affecting quality and cost * Factors affecting the usability of complex documents in image form * +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Donald WATERS, head of the Systems Office, Yale University Library, reported on the progress of a master plan for a project at Yale to convert microfilm to digital imagery, Project Open Book (POB). Stating that POB was in an advanced stage of planning, WATERS detailed, in particular, the process of selecting a vendor partner and several key issues under discussion as Yale prepares to move into the project itself. He commented first on the vision that serves as the context of POB and then described its purpose and scope. WATERS sees the library of the future not necessarily as an electronic library but as a place that generates, preserves, and improves for its clients ready access to both intellectual and physical recorded knowledge. Electronic tools must find a place in the library in the context of this vision. Several roles for electronic tools include serving as: indirect sources of electronic knowledge or as "finding" aids (the on-line catalogues, the article-level indices, registers for documents and archives); direct sources of recorded knowledge; full-text images; and various kinds of compound sources of recorded knowledge (the so-called compound documents of Hypertext, mixed text and image, mixed-text image format, and multimedia).
