Free Books from Other Publishers

Introduction

We have long supported publication of free documentation (free in the sense of freedom—we don't mean gratis). free software needs free documentation because you must be free to copy, change and redistribute the documentation along with the software. To qualify as free, the documentation must be released under a free documentation license.

We publish a number of free books of documentation ourselves. You can order printed copies of our books, and browse them online. We have been doing this since around 1986.

Some commercial publishers are also publishing free books. (Like ours, these books are free in the sense of freedom; the commercially printed copies are sold.) On this page, we list the ones we have come across. If you find out about a free book that is not listed here, please let us know by writing to <free-books@gnu.org>.

Some of these publishers (e.g., Network Theory Ltd) do not trade directly. Their books can be obtained from many suppliers throughout the world, but please don't order them, or any other book, from Amazon!
