I'm selling off a lot of books that are just taking up room on my bookshelves. They're mostly science fiction and fantasy -- Isaac Asimov, Anne McCaffrey, Arthur C. Clarke, David Eddings, Frank Herbert. I take Bitcoin and several altcoins as payment. You can see everything that I have available in my blogstore, here:
