@worldsendless @fsf @dff it's not much but there's a tiny section about non software works here https://www.gnu.org/licenses/#OtherWorks

@worldsendless I've seen some creative works that aren't software given GPL style licenses. However, licenses such as the #CreativeCommons ones tend to be more widely used for a variety of reasons. Was very impressed with Lawrence Lessig's book which talks about the Creative Commons and mentions Free Software as an inspiration: https://www.feedbooks.com/book/2750
