----------------------------Original message---------------------------- Very informally, the UC map libraries have depended on UCLA and to some extent UCSB (only since 1969 in the latter case) to keep superseded vendor catalogs. We find them to be especially useful in those cases where vendors stop listing titles no longer available for sale in their current catalogs. There was at one point a general plan to catalog as collections UCLA's extensive collection of ephermeral material; a substantial number (?perhaps all) of the map-library acquisitions lists were indeed cataloged.
