Mainly audio... I haven't checked out the supposedly "Django, Chet and Les Paul" Limehouse blues but regardless, besides something for everyone, the animation category contains some Disney RKO stuff that was banned as well as released to the public domain because it was made for the government.
Not to mention hundreds of classic old tv shows. Fun to wander around in.
