I have books and more. If your recycling center has a place where people can leave things to "swap", now is the time to look. Thrift stores are also a good source. When someone says "I don't believe in that" or "That's a conspiracy," it helps to have a book to return to and validate your thoughts. Be prepared. You can show people the evidence and they will still deny it and may even act out toward you. I have experienced this several times. Over time I have come to realize this project is for me, to remind myself I am on the right path, and I have nothing to prove to the deniers.
