GEN: bib records

[Margaret Mary Bedle <mbedle@UDEL.EDU>]

   I use Unison in our  school library. And I was wondering wheteher in
entering your bib records on your computer system, do you place all
your copies of a title under one record, or do you use a new book whenever
you acquire another copy of a title from a different publisher?  If you
hand a paperback copy and a harback copy of Clancy's The Hunt for Red
October"  would you use two separtae book records?
  I prefer having all copies ofa book under one record, but often the info
for the Marc records would be different ( publishing and description).
How to you handle this?

TIA
