Steps Toward an On-Line Union List
This paper describes the on-line union list file currently being developed by the University of Pittsburgh and other libraries of the Pittsburgh Regional Library Center. Present procedures and future plans are described. The on-line holdings format for local data records agreed upon with OCLC is reported. It is expected that concepts worked out for the Pitt/PRLC on-line union list records will be precedent setting for other future on-line union list efforts.
