On our support website, at the bottom, we have a list of OpenOffice-related books:
http://www.openoffice.org/support/ As you see, we have links to 3rd party pages for purchasing the books, usually Amazon or Lulu. I'm in the process of updating this page, as part of adding a list of consultants, and it occurred to me that we should probably think about how Shane's draft linking policy applies to books: http://www.apache.org/foundation/marks/linking One way to think of it is to treat the publisher or author (for self-published books) as the "consultant" in the terms of the policy. They are the ones providing the service, via their book. So we would allow linking to the author's website or the publisher's website which describes the book. But we would not link to Amazon, since they are a retailer, not the author or the publisher. Otherwise, same criteria as consultants -- factual list, respect trademark, impartial, rel="nofollow", etc. Does this make sense? -Rob
