I’ve used Past Perfect for many years and find the different catalogs useful. After all, the database will search them all once you learn how to use the program. I used Objects for 3-D items/artifacts, Archives for mainly unpublished works (letters, diaries, newsletters, personal papers, maps etc.) and put published books and magazines in Library. We have a small library. All photographs and photo albums go in Photos as well media (tapes, DVD, CD-Rom, etc.). Everything begins at the Accession level though. Well, except for the digitized oral histories.
