I need to make sure the response is helpful but complies with copyright laws. So I'll summarize the possible resources, mention the potential copyright status, and suggest legitimate ways to access the content without violating laws. Also, if there's a newer edition or a similar book that's more recent, pointing that out could be useful. But without specific info on an updated version, that's hard. So the response should be clear, informative, and guide the user in the right direction without encouraging piracy.
