I guess the question is, how do you prevent one person from getting a PW and then telling 100 friends, so they can read the site for free? (just a bit negative, but it is a valid question)

With the book, you have it and it would cost more to copy than just buy the dang thing.

I have seen others who make CDs of their information, and I don't see copies being sold or massive trading. The only things I copy are for my own archives.

A guide is just a guide. It's also good reading. I have taken TCR with me on trips and when I find a chip I can just look it up. I wouldn't be able to carry a laptop and web connection to a coin show or dealers shop.

I'll go double for the good reading part.
