At "Kinkos/FedX" I had them put a coil binder on it for about $5 US. This definitely is the best method I've found for study and reference books that aren't thicker than 2 inches or so.
They can usually do it while you wait. (about 15-20 min.)
P.s. The coil I chose is about 5/8" - 3/4" in diameter. Just big enough to easily turn the pages.
