Another solution is trying companies buying old media. I finally got rid of Lisp in Small Pieces, which I would never have worked through anyway and some other comparable book I cannot remember for double-digit Euros!

It's hit-and-miss, though. I see no rhyme and reason in which books they're interested in, and the prices.

Just the day before yesterday I took some cooking books in pristine condition to the library. They used to have a book-swapping box outside. It was gone.

I went in (not too thrilled with the prospect of lugging it all back home) and asked about it. No, they don't have it anymore. I can put my books in the "free section" inside.

I did that, the librarian walked by to take a look and snatched the books away. "They are good, I'll see whether we can use them for the library. Usually we only get books we throw away immediately."

Lisp in Small PIeces is one of the best books I've ever read. Besides being a deep reach into programming decisions it is one of the best examples of a literate program.

By "getting ride of it" I assume you put it into a glass case on your office wall. I admit it does deserve such a place of pride.

I just donated 200+ books. They were ecstatic to receive them. It's a reasonably good way to go. Plus, what they don't want or won't sell, then they can decide what to do with so that I'm not a book murderer. My book conscience is clean.
