the easiest way to self bound a book, imho, is perfect bind. all you really need is a couple 2x4s, a couple C-Clamps and brush on some binding glue with a foam paintbrush. although this way can become a bit of a pain in the ass if you are doing to many or to little pages. the best way is to just go to a store, such as staples or officemax, and ask them to bind it for you, also most print shops do binding and a quick google search could probably turn up a few binding specialty shops.
