Digitizing Legacy Documents: A Knowledge-Base Preservation Project. Anderson, Elizabeth Atkinson, Rob Crego, Cynthia Slisz, Jean Tompson, Sara Cataloging Computer Selection Computer Software Data Conversion Grants Optical Data Disks Preservation Scientific and Technical Information World Wide Web Describes efforts at the Fermi National Accelerator Laboratory (Fermilab) to digitize their legacy collection of scientific and technical reports to make them available via the Web and CD discs. Topics include a grant from the Illinois State Library for funding, hardware and software, scanning documents, CD-ROM recording and organization, and cataloging. (LRW)
