 MISC: When Marty wakes up in his bed in 1985, in the bookcase behind  his head theres a yellow magazine named "RQ". This stands for  "Reference Quarterly", a trade journal of reference librarians. In  the DVD commentary track by producers Bob Gale (qv) and  Neil Canton (qv), they admit that the set dresser made a mistake  in putting it in, as a teenager would have no reason to have a copy  of "RQ".
