Just a short post about a great resource of medical books. The Textbook Revolution is a collection of free medicine/health-related books. The FAQ says:

Yes, the books are offered for free by their authors/copyright holders, at least to view online. Some of the books have restrictions on printing, sharing, reusing them, etc. Please respect these restrictions. There’s no catch, but because this is a collection of other people’s work, each item will have different restrictions.

The maintainer of the site has a blog as well: The Stingy Scholar.
