About 100. I'm trying to cut back. I have boxes of books that I've never read, such as some of my college textbooks. Books that are in moving boxes, never opened since my last move. Many of those texts are obsolete, in the sense that I don't remember the material well enough to favor my old book over just looking it up online. Classical mechanics would be an example of that. Some books I keep for nostalgia, such as The Art Of Electronics, which was life changing for me. But I'm trying to be more selective of those books. I read a lot of fiction, history, biography. Some of those books I get as gifts, and try to pass them on to another reader. I try to make use of my public library when possible, because I still do prefer reading from a book rather than electronically. I've moved most of my sheet music to electronic. That's an area where technology is actually an improvement.
