The Hubbell Library and other NOPL branches have audiobooks on CD and cassette. But now the New Orleans Public Library also has audiobooks and eBooks that you can download directly via their Web site. Download them and listen to them on your computer or on your MP3 player (except iPod). You'll find them here:

Audiobooks and eBooks on the NOPL Web site

Unfortunately, those audiobook files won't work with iTunes or on an iPod, the most popular MP3 player!

For iPod

Fortunately, there are other sources of free downloadable audiobooks that work just fine on iPod. Here are a few Web sites where you'll find hundreds of titles:

LibriVox volunteers record chapters of books in the public domain and upload the audio files for the rest of us. Their goal is to make all public domain books available as free audiobooks. More than 800 titles are available.
Project Gutenberg
The oldest digital library. A volunteer project to digitize, archive, and distribute cultural works. Over 20,000 titles, including digital texts, eBooks and audiobooks, in many languages.
MP3, iPod and DVD audiobooks. Adventure, detective, horror, classics, children's, non-fiction, philosophy, etc. Several hundred titles.
The term podiobooks was coined to describe serialized audio books made available in podcast format. Listeners can choose to receive the episodes of their books via an RSS feed or by listening to episodes by directly downloading them from the site.
Free Classic Audio Books
Several dozen titles.
About three dozen novels, short stories, poems, children's stories and historical documents. You can download them, or listen while reading the text on-line.
