My friend sometimes shops at the Goodwill by-the-pound store, otherwise known as "The Bins." I've been to The Bins a couple of times, but the shopping experience is not for me. Not surprisingly as a used book dealer, I'm a proponent of re-use, recycling, and buying used, but the couple of times I've been I've always wished I had worn gloves and felt like I needed a shower afterward.
Giant wheeled bins are filled with piles of clothes, household goods, and, yes, books. The customers are a mix of regular people, dealers, and crazy people, particularly those after books. My friend usually concentrates on vintage clothing and she's found some good scores, like a Pendleton jumper, or a tapestry of a pastoral scene that she re-purposed into a skirt. When she found this scrapbook, she passed it on to me.
This scrapbook also included a number of loose items, yet-to-be-pasted, which makes it a candidate for the "found in books" category.
