Here is a way to support Robert Anton Wilson's writings, even if you have no money and little time: Check his books out of the public libraries you patronize.
All libraries have a limited amount of space, and even the most poorly-funded ones add new materials this year. This means that every library has a weeding process to get rid of books on the shelf. It might have a policy, for instance, to get rid of every book that hasn't been checked out in the last 18 months. When you check out a book by RAW, you are increasing the chance it will remain on the shelf to be discovered by other readers.
