I was at a small shop that was going out of business the other day and it was the last day that they would be open, so everything absolutely had to go. There was not much left except for an old dusty looking stack of books sitting in the corner. I wandered over and noticed that they were encyclopedias from 1888. The whole stack of about 9 or 10 books was only $15 so I had to buy them. They were not in the best condition, but I thought books over 100 years old were really cool. Unfortunately I didn't get the whole set, but the ones that I do have are full of very interesting things from that era. All in all I think it was a good purchase.
