The Gerhard Mansbach Collection of Technology Manuals primarily consists of technology reference and technical manuals. Most manuals in this collection were created by the International Business Machines Corporation (IBM), though there are also manuals created by Borland International, Commodore International, Digitial Equipment Corporation, Government Publications, Honeywell, and Intel. Also included in the collection are materials relating to the Cape Cod Tourist Study and the Overlay Assistant project which Mansbach worked on. The collection also contains several books, most of which are about programming, as well as demo software floppy disks for the Overlay Assistant project, and software disks for Borland International and Boston Computer Society products.
