University Libraries at Virginia Tech is working with OCLC to test extracting
 data and tape loading USMARC holdings from our VTLS system into the OCLC union
 list of serials. Having spent over five years creating MARC holdings records
 it just doesn't make sense to manually enter the data again into yet another
 system. If such a load into OCLC is possible then the remifications are are
 reaching--the reverse procedure should work to extract information from the
 union list to create MARC holdings records.   Why should it work?

 What follows is a chart that shows data from the MARC holdings format that
 should be loaded into the OCLC union list.  Unfortunately, the delimiters
 did not upload from the WordPerfect file but I think it shows the corelation
 between The Format and the Union List information.
