Spying on libraries

OK, I admit it. I do a little bit of library spying. My novel is still pretty "small-time". So, there are only about 5 or 6 libraries that I know have my book on hand. I like to check them out when I'm bored sometimes and see if my book is getting read or if it's just sitting there on the shelf collecting dust. For the most part, it seems to be checked out pretty often, which is good! I still find it exciting when I hear that my book is being read. I guess there's no guarentee that if it's checked out that it actually gets read, but I like to assume it does....
