This category is for articles about licenses which:
- Contrary to the usual application of copyright law, aim to enable each recipient to help himself and to cooperate with others, and
- Require that modified versions be distributed wholly under the same licence ("share and share alike")
Note: this category differs substantially from Category:free software licenses in that it is not limited to software, and not all free software licenses are copyleft (some are permissive, like those of BSD and MIT).id:Kategori:Copyleft nl:Categorie:Copyleftlicentie
