Check for an on-line catalog at the nearest [large] university near you. I use Arizona State at http://catalog.lib.asu.edu. But from your title, I'd check www.isa.org first (or ISA at 919-549-8411) - it sounds familiar, though there might be a later rev.

Johnson, 1982. Can anyone tell me who the publisher is or where I can obtain a copy? Or, does anyone know of a web site where you can search by ISBN number? Thanks. Doug Pauls CSL [log in to unmask]
