THE MESSAGE BELOW IS FROM ADMINISTRATIVE NOTES,
VOL. 17, #08 (June 15, 1996)
SPATIAL DATA SUPPLEMENT TO
RECOMMENDED MINIMUM SPECIFICATIONS FOR
PUBLIC ACCESS WORK STATIONS IN FEDERAL DEPOSITORY LIBRARIES
In the May 15, 1996 issue of Administrative Notes the Library
Programs Service (LPS) published the "Recommended Minimum Specifications
for Public Access Work Stations in Federal Depository Libraries." Those
specifications are intended to assist depository librarians who are
planning purchases of new personal computers (PCs) for public use in
Federal depository libraries, and should be adequate for most general FDLP
electronic products.
However, as noted in that article, we were advised that work
stations which conform to those minimum specifications may not be adequate
for electronic spatial data, to run geographic information system (GIS)
software, or to print maps from electronic sources. The Cartographic
Users Advisory Council (CUAC) has assisted LPS in the development of this
supplemental set of specifications which support spatial data
applications. All of the caveats concerning work stations and software
expressed in the May 15, 1996 article also apply to depository libraries
which elect to serve the public with electronic spatial data.

3.3 or higher). Device driver for CD-ROM drive and MS-DOS CD-ROM
extensions.
Communications Package which supports multiple file transfer protocols;
several terminal emulations such as ANSI-BBS, TTY, VT-100. Data transfer
rates up to 28.8 kbps. Supports Hayes "AT" compatible modems; manages
telnet sessions. Consider ability to "script" log-on files.
Client Software World Wide Web graphical browser with forms support. ANSI
Z39.50 compatible, GILS-aware WAIS client. Consider EINet WinWais
customized for GPO Access.
Viewers PDF file viewer. GIF, GEOTIFF, TIFF, and JPEG graphics viewers.
Applications Software Options
