We seem to have a problem with licences like the GFDL or the CC-by-sa, for which potential users seem to be uncertain what constitutes derivative work. Our [[Commons:Reusing content outside Wikimedia]] says "You must make your version available under CC-BY-SA." and "Any derivative works must stay under the GFDL. When using a photo placed under the GFDL licence as part of a larger work, the larger work must also be released under GFDL for usage to be within the license terms." This seems to be a problem for people who want to use an image in a book and cannot release the entirety of the book under the GFDL or the CC-by-sa.
I asked the FSF specifically about what constitutes "the larger work", and (as noted in the FAQ) they said ask a lawyer if in doubt. We really can't give any better advice than that.
