Z:gnu-www-ja-using-gfdl--8a9a6c-When a commercial manual is fr/en

When a commercial manual is free and relates to the GNU system, the GNU Project can recommend it to the public. So if the authors or publisher set up a web page to describe it and/or sell copies, we can make a link to that page from www.gnu.org/doc/other-free-books.html, provided the page meets our usual criteria (for instance, it should not link to other pages about nonfree software or documentation, and should not be obnoxious about trying to persuade people to buy). Please inform  &lt;webmasters@gnu.org&gt; about such pages.
