It takes me a while to read the books I have as well. I've bought lots of books than I haven't been able to read yet and my list of books to buy and read keeps growing as well. Another thing that adds to the amount of time it takes me to read a book is that I'm a very meticulous reader. I like looking up and cross referencing anything I don't understand, so for me that means looking up lots of stuff. I wonder if other people do this as well.
