According to a recent blogpost at The Private Library, every year approximately 30 English-language movies that are based on books are released in the United States.
To keep up with the newest releases – such as several movies that will be premiered in Atlanta theatres later this month – you can consult Bookreporter.com’s Books into Movies.
To check on the bookish origins of older movies – according to the Internet Movie Database, over 28,500 of them – you can check one of the numerous databases listed in the Booklover’s Toolbox under the heading “Movies Based on Books.”
The Central Library (and the Sandy Springs Branch) also own a printed resource that you could check for information on book-based films released between 1928 and 2001: Enser’s Filmed Books and Plays.
You might just find yourself including in your reading for 2010 the book that inspired one of your favorite films. Chances are that your local library will own a copy of it; if it doesn’t, you can ask for it via inter-branch or interlibrary loan.
