eBooks are freely available from OPL - we have a number of different collections and formats, all listed here. And, we'll help you get started with ebooks and such at the Main Library - just come in and talk to any librarian, or come to our monthly program - every last Wednesday of the month, we'll walk you through our various e-collections. You can bring your device to follow along. Remember, you'll never get a fine on e-materials!
There are other sources as well. One of the most popular sources for free eBooks is Project Gutenberg, which includes more than 45,000 eBooks, all free; all titles are in the public domain. There's also a number of digitized sheet music available - the focus there is on chamber music, mainly titles by Brahms and Beethoven. There's also a good listing of more than 600 free ebooks at OpenCulture.com, a great site for free cultural and educational media online.
Another, often overlooked resource, is the federal government. While you won't find fiction titles, Publications.USA.gov is operated by the Federal Citizen Information Center (FCIC) and provides federal government publications that are quite helpful. There's a variety of formats (print, online, PDF, and ePub/Mobi formats) and topics, including animals - both wildlife and pets, food, consumer protection, housing, and of course, various federal programs. Some of the print offerings aren't free, but all the online content is free. Most of the content is available in Spanish, as well. The most popular content so far? It's their Consumer Action Handbook, with more than 162 pages of helpful consumer advice and contacts. There's three recipe books, also, with useful menu planning guides.
