I have at least 30 books about dogs (not including the fiction ones!), three about rodents, at least 5 about Psychology, two about nutrition, two about global warming, one about medicine... Er. I like collecting information. So, I could keep going. People tend to know I like knowledge, most don't know how many nonfiction books I actually have. I, also, like to save old text books.

On top of my nonfiction books, I have a collection of books so vast that I literally have no room for them in my house anymore. My room is overfilled with books of all sorts.
