A good operating system includes documentation. If the operating system is free, this documentation needs to be free as well. The GNU system and other free operating systems do not have all the documentation that they need; there are major gaps. One of the reasons these gaps persist is that many people think that non-free documentation is sufficient--people do not recogize the gaps as a real problem, because they think that non-free documentation is sufficient. When users buy non-free manuals about GNU software, this just encourages writing more of them--instead of the free manuals (free in the sense of freedom) that we need. So the GNU project hopes that you will not buy such books if you can possibly help it. The decision of what you buy is up to you. But whatever you decide, please don't advertise these books on our newsgroups and mailing lists.
