But that is not all!
Audiobooks (listed as "Spoken" in the library catalog) and E-books are also available from the Omaha Public Library.  Audiobooks are a great way to pass the time while driving to those far-away conventions, and you can carry a lot of E-books when you're off on vacation.
Some titles are even available to be downloaded to your computer without having to go any of the individual branches.

Go to the Omaha Public Library website.

From the pull-down menu for Catalog & Services, click Library Catalog.  This will pull up the Search Catalog page.

Chose the Advanced tab (5th tab from the left) to enter their advanced search engine.

Enter your SUBJECT keyword (the genre or subject, for example, science fiction, werewolf, fantasy, horror, Luke Skywalker, Middle Earth, dragons, occult, etc.).

Refine your search by selecting a media type (Spoken CD, E-Books, etc.) from the selection list labeled "by Item Type."

Click the red "Go!" button.
