If a product is no longer commercially available ( parts list cd) how are potential users of such supposed to be able to reference items for the product to which it refers? Does this lack of availability affect how the original (the cd) copyright is applied? In this case what are users supposed to do and what would they gain by being able to access the cd other than trying to sell it? I would think that sharing within a closed environment ( the 260's) with a declaration to not use for commercial purposes for a very limited market (260/V8) should be considered acceptable.
