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).
POB is looking particularly at images and an image library, the uses to which images will be put (e.g., storage, printing, browsing, and then use as input for other processes), OCR as a subsequent process to image capture, or creating an image library, and also possibly generating microfilm.
While input will come from a variety of sources, POB is considering especially input from preservation microfilm. A possible outcome is that the film and paper which provide the input for the image library eventually may go off into remote storage, and that the image library may be the primary access tool.
The purpose and scope of POB focus on imaging. Though related to CXP, POB has two features which distinguish it: 1) scale—conversion of 10,000 volumes into digital image form; and 2) source—conversion from microfilm. Given these features, several key working hypotheses guide POB, including: 1) Since POB is using microfilm, it is not concerned with the image library as a preservation medium. 2) Digital imagery can improve access to recorded knowledge through printing and network distribution at a modest incremental cost of microfilm. 3) Capturing and storing documents in a digital image form is necessary to further improvements in access. (POB distinguishes between the imaging, digitizing process and OCR, which at this stage it does not plan to perform.)
Currently in its first or organizational phase, POB found that it could use a vendor selection process to facilitate a good deal of the organizational work (e.g., creating a project team and advisory board, confirming the validity of the plan, establishing the cost of the project and a budget, selecting the materials to convert, and then raising the necessary funds).
POB developed numerous selection criteria, including: a firm committed to image-document management, the ability to serve as systems integrator in a large-scale project over several years, interest in developing the requisite software as a standard rather than a custom product, and a willingness to invest substantial resources in the project itself.
Two vendors, DEC and Xerox, were selected as finalists in October 1991, and with the support of the Commission on Preservation and Access, each was commissioned to generate a detailed requirements analysis for the project and then to submit a formal proposal for the completion of the project, which included a budget and costs. The terms were that POB would pay the loser. The results for Yale of involving a vendor included: broad involvement of Yale staff across the board at a relatively low cost, which may have long-term significance in carrying out the project (twenty-five to thirty university people are engaged in POB); better understanding of the factors that affect corporate response to markets for imaging products; a competitive proposal; and a more sophisticated view of the imaging markets.
