In media, which includes textual, audio and visual content, free licensing schemes such as some of the licenses made by Creative Commons have allowed for the dissemination of works under a clear set of legal permissions. Not all of the Creative Commons’ licenses are free: their permissions may range from very liberal general redistribution and modification of the work to a more restrictive redistribution-only licensing. Repositories that exclusively feature free material provide content such as photographs, clip art, music and literature[4].
