The 1985 Mississippi public television production Tomes & Talismans is a wonder to watch.
As a librarian, I can really appreciate it. One of my principles of collection development is that it should be possible to rebuild human civilization up to the level of 19th Century America from the information contained in the print collection of any mid-sized library. I have used this principle to argue for retaining old, uncirculated books, such as general encyclopedias of science and engineering, which would be essential for the reconstruction of a destroyed human society.
Thus Tomes & Talismans strikes a chord with me. The 13-episode series, which you can watch for free here, depicts an Earth conquered by alien colonizers called the Whipers. Humanity has chosen to evacuate to another star system. One librarian has remained behind in order to ensure that her library's collection has been preserved and its organization scheme made comprehensible to future generations.
I have watched only the first episode, but it appears that the show tells a dystopian science fiction story while teaching viewers how to make find available information in typical public libraries.
