Thanks! I printed up stickers and put them on the first page. It says "Bitcoin Book Drop" and just says "Find, Read, Drop". Writing a cool note is a good idea. I'm also working on an orange pill pamphlet that has some really good introductory info about Bitcoin and gives links to good resources.. I might start slipping those in the books too.

Amazing! I found a book once and it had handwritten instructions to read and drop. And you could write a note under it for the next finder. It gave the whole experience a very personal touch.
