Sesame Street, 1970s? http://www.youtube.com/watch?v=ZJlkplvYdgA Other muppetational library shenanigans: At Your Library, and Rock and Roll Readers from Sesame Street, At the Library (Michael Sporn) and Kermit the Frog Visits from Reading Rainbow, Library and Words from The Electric Company (turns out Easy Reader’s “favorite girl” is a librarian!), and The Library from The Muppet Show. (All fictional shenanigans.)
