Mindfulness in Plain English discussion

This classic book is available online for free, but many others on the subject of mindfulness are not free and can be expensive.
Shouldn't more books like this be freely available?
Well one website I found lets it users swap mindfulness books, audio and video for free:
Mindfulness Meditation for Beginners
What an excellent idea, what do others think?

You mean like a library or something?

a library is for borrowing books etc, this is for swapping them

You can sign up and add books you're interested in but can't afford to your wishlist, and the site then tells you when anyone else is offering any of them for a swap!
