I once bragged about a 40 hour week in the shop and then realized I had counted Tuesday twice. So yeah, I get the whole doubting yourself thing. Charts are just a way to track the chaos, and past a certain point the number is more about surviving the shift than any real measure of skill. 500 covers in eight hours with 38 seats means you were basically a machine, and the crew is just jealous they didn't get to write it down first.

I did almost the same thing two summers ago in Milwaukie, just off Concord, and I counted 31 books gone in about 90 minutes. My neighbor Deb took six romance novels and came back the next week with a grocery bag of her own to add, so some folks do get it. The one thing I learned is to write the date on the sign, like FREE BOOKS SAT ONLY, because otherwise people start dropping their old junk there at 10pm like it is a dump. I also stopped putting out anything nice because a couple of good hardcovers walked off the first time and that bugged me more than it should have. Try the swap table once and see what happens, but keep your hopes low on the trading part and you will be fine.
