In the hardware realm, a large-format scanner is a necessity (a point made by GIS support personnel at Williams, Dartmouth, Harvard, Mount Holyoke and Smith), and would be of great value to a range of departments and offices --notably B&G and Special Collections, as well as the collection of paper maps in the Geology department (scanning the wealth of maps in W&L collections would make them accessible for instruction; georeferencing them would allow incorporation into GIS projects). The Vidar scanner offers easy connection to large-format printing. See Harvard's Map Collection for a description of one service model, and Rutgers tutorial for further practical details on the Vidar scanner. Rutgers' Scholarly Communication Center is an interesting model for provision of a range of services.
We have server space for dedicated GIS use, management of which will involve collaboration among library, ITG, and UC network personnel.
