And honestly, unless they were historic manuals, you're not likely to get much money from selling them. Most folks are happy with reading online docs for anything current.
About 20 years ago I did get a whole set of the v6.12 manuals from someone who was giving them away on SAS-L. I only had to pay for shipping. Somehow along the way I managed to lose them in a move. Or perhaps my wife "lost" them in a move. She didn't always appreciate dedicating a full bookcase to SAS manuals in our tiny apartments. I still have plenty of SAS books (on bookcases up in the attic, out of sight from polite company), but not many manuals. In fact I think my only manual is SAS Users Guide 1979 edition. I couldn't resist when a friend offered it to me.
