So, you’ve got yourself an eBook reader, smartphone, tablet, or other portable device and you want to put some eBooks on it to take with you. There are many options for obtaining free eBooks as well as purchasing, borrowing, or even renting eBooks.

We’ve listed some sites that allow you to download free eBooks directly or be notified when eBooks are available for free or for a discounted price on popular eBook sites. If you can’t find the eBooks you want on the free sites, there are several sites that allow you to purchase current, best-selling  eBooks singly or through a monthly service. There are even special sites for lending and borrowing Kindle and Nook books with other readers across the U.S. We’ve also listed a couple of sites dedicated to searching for PDF eBooks, documents, etc.

Kindle Textbook Rental

Library To Go (and other libraries lending eBooks)

Now you can check out library books as eBooks without ever setting foot in a library. The Library To Go website mentioned here is for libraries in the Northern California area. Go to the website for a library near you to find out if they offer eBook lending and how to borrow eBooks from them.

Library To Go uses the Adobe Digital Editions software for eBooks and OverDrive Media Console for audiobooks. You can borrow eBooks in Kindle format (for U.S. libraries), EPUB, and PDF. Kindle books can be delivered to both Kindle devices and Kindle reading apps on other devices. EPUB eBooks have “reflowable” text that fits any screen, so they are good on most mobile devices. PDF eBooks have fixed text, but you can zoom in on the text to create a large-print eBook.

Library To Go allows you to check out up to three titles and your cart will hold up to 15 titles. This differs, depending on the library. For example, the Ventura County Library in California (powered by OverDrive Media Console) allows you to check out up to five titles and your cart will hold up to seven titles. The lending period can vary from title to title. Titles are generally removed from your cart after 30 minutes so that other users can have the chance to check them out.

On the Library To Go site, you can place up to four titles on hold at one time. They send you an email when a title becomes available. You have five days to check out your hold after we email you notification that it is available. On the Ventura County Library site, you can place up to five titles on hold at one time and you have four days to check out the books on hold once they become available.

NOTE: Use the OverDrive service to find a public library in your area that allows you to check out books on your eReader. This is a relatively new service, so not all libraries are connected, yet. Check both the OverDrive site and your local library’s website to see if eBook rentals are available at your library. Also, be sure to check out the eBook lending policies for your local library.

Open Library

Open Library is an open, editable library catalog, building towards a web page for every book ever published. Once registered on the Open Library site, you can borrow up to five eBooks for two weeks each from the growing collection of mainly 20th century titles available now. Each title in the library can be borrowed by one user at one time and can be read in a web browser, or in Adobe Digital Editions, as a PDF or ePub.

eBookFling

eBookFling makes it easy for readers across the U.S. to borrow and share their Kindle and Nook eBooks. Earn credits by lending your eBooks, and use those credits to borrow eBooks from other users. The eBooks are automatically returned in 14 days. If you don’t want to lend an eBook, you can pay to borrow one.

Lendle

BookLending.com

BookLending.com is a website that matches lenders and borrowers of Kindle eBooks.  To participate in lending and borrowing Kindle books, you must first register as a user on the site or connect using Facebook Connect.
