Welcome to AAPK.
I do not know of any book that gives useful information about Buck Creek knives.
The difficulty with this brand is how to tell the original ones, 1976 to about 1989, from those that were made later, in Germany, but might not be to the same quality standard. The Buck Creek knives being made now are marked China. These are not collectible at this point but might be a very good user knife.
Watch out for off gassing of the B.C. knives with celluloid handles. I have had at least 10 of these off gas and deeply corrode the blades and eat through the brass liners.
I suggest that you only keep the stag and bone handled ones. Do not keep the cell handled ones. Sell them cheaply now or at a minimum separate them from being close to any other knives.
