Based on the Book

Anyone working in a library will tell you that books which are made into movies are popular with readers.  You will see long holds lists for books that have been just been made into movies, no matter how old the book it.  Woe is the acquisitions department when a blockbuster film is based on a book that is no longer in print or wide distribution.

At my library, we have a "Raves and Faves" program which features sure-fire reads in greater quantities which are often displayed near the entrance so that customers can quickly grab a great read.  We included "Wild" by Cheryl Strayed and "Still Alice" by Lisa Genova.  Needless to say, both titles quickly exited the library to fill holds.

A display of books and the films they are based on is a quick win for your collection as readers and watchers will be intrigued to see these collected together.  Good readers' advisors probably do not need a lot of aids to find these quickly but there are a lot of resources out there to find these items.

Mid-Continent Public Library offers 1450 book titles and the movies they inspired.
