Here are reviews of some non-fiction books I've read. Just about any subject tickles my fancy, and some of these books came out some time ago. I don't write a book review about every book that I read, although I'm more likely to write one for the non-fiction books than the fiction.
I suspect that you'll never catch me writing a review on a computer book, even though I read more of those than of any other variety. For whatever reason I've never felt it necessary to comment on one of them at any length.
