Do slowly degrading B movies have academic value? Yale University librarian David Gary thinks so.

Gary joins Shad to explain how he ended up with thousands of horror and exploitation films on VHS tape, including Bloodeaters (1980) and Slumber Party Massacre (1982). From the box art to the tactile experience, the librarian argues there's plenty to preserve for younger generations.

He details the joys and challenges of rewinding back to our cinematic past.
