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,
download them from the
/gnu/Manuals directory on our ftp
site and browse them online.
We have been doing this since around 1986.
More recently, some commercial publishers have begun publishing free books. (Like our books, these are free in the sense of freedom; the commercially printed copies are sold.) On this page, we keep a list of these books that we have come across. If you find out about a free book that we don't have listed here, please let us know by emailing us at <free-books@gnu.org>.
Newer listings are placed at the top of this list.
Comments on these web pages to webmasters@gnu.org, send other questions to gnu@gnu.org.
