I got 3 more packs of those small boxes from Staples. I underestimated how many I would need! Hardback books aren't really the problem, but all the gaming books I own are very heavy and oversized. I should have enough now, however, I got 18 more boxes. Thats a total of 54 book boxes and I already had 54 larger boxes that I used for paperback books, dvds, and everything else. That's a lot of boxes.
