Project Open Book, the Yale University Library's effort to convert 10,

000 books from microfilm to digital imagery, is currently in an advanced

state of planning and organization. The Yale Library has selected a

major vendor to serve as a partner in the project and as systems

integrator. In its proposal, the successful vendor helped isolate areas

of risk and uncertainty as well as key issues to be addressed during the

life of the project. The Yale Library is now poised to decide what

material it will convert to digital image form and to seek funding,

initially for the first phase and then for the entire project.

The proposal that Yale accepted for the implementation of Project Open

Book will provide at the end of three phases a conversion subsystem,

browsing stations distributed on the campus network within the Yale

Library, a subsystem for storing 10,000 books at 200 and 600 dots per

inch, and network access to the image printers. Pricing for the system

implementation assumes the existence of Yale's campus ethernet network

and its high-speed image printers, and includes other requisite hardware

and software, as well as system integration services. Proposed operating

costs include hardware and software maintenance, but do not include

estimates for the facilities management of the storage devices and image

servers.

Yale selected its vendor partner in a formal process, partly funded by

the Commission for Preservation and Access. Following a request for

proposal, the Yale Library selected two vendors as finalists to work with

Yale staff to generate a detailed analysis of requirements for Project

Open Book. Each vendor used the results of the requirements analysis to

generate and submit a formal proposal for the entire project. This

competitive process not only enabled the Yale Library to select its

primary vendor partner but also revealed much about the state of the

imaging industry, about the varying, corporate commitments to the markets

for imaging technology, and about the varying organizational dynamics

through which major companies are responding to and seeking to develop

these markets.

Project Open Book is focused specifically on the conversion of images

from microfilm to digital form. The technology for scanning microfilm is

readily available but is changing rapidly. In its project requirements,

the Yale Library emphasized features of the technology that affect the

technical quality of digital image production and the costs of creating

and storing the image library: What levels of digital resolution can be

achieved by scanning microfilm? How does variation in the quality of

microfilm, particularly in film produced to preservation standards,

affect the quality of the digital images? What technologies can an

operator effectively and economically apply when scanning film to

separate two-up images and to control for and correct image

imperfections? How can quality control best be integrated into

digitizing work flow that includes document indexing and storage?

The actual and expected uses of digital images--storage, browsing,

printing, and OCR--help determine the standards for measuring their

quality. Browsing is especially important, but the facilities available

for readers to browse image documents is perhaps the weakest aspect of

imaging technology and most in need of development. As it defined its

requirements, the Yale Library concentrated on some fundamental aspects

of usability for image documents: Does the system have sufficient

flexibility to handle the full range of document types, including

monographs, multi-part and multivolume sets, and serials, as well as

manuscript collections? What conventions are necessary to identify a

document uniquely for storage and retrieval? Where is the database of

record for storing bibliographic information about the image document?

How are basic internal structures of documents, such as pagination, made

accessible to the reader? How are the image documents physically

presented on the screen to the reader?

The Yale Library designed Project Open Book on the assumption that

microfilm is more than adequate as a medium for preserving the content of

deteriorated library materials. As planning in the project has advanced,

it is increasingly clear that the challenge of digital image technology

and the key to the success of efforts like Project Open Book is to

provide a means of both preserving and improving access to those

deteriorated materials.
