Additional eBooks,outside your Overdrive quota are always available from the Overdrive site via Project Gutenberg.
Project Gutenberg (PG) is a volunteer effort to digitise and archive cultural works, to encourage the creation and distribution of eBooks. It was founded in 1971 by Michael S Hart and is the oldest digital library. Most of the items in its collection are the full texts of public domain (copyright free) books. The project tries to make these as free as possible, in long-lasting, open formats that can be used on almost any computer. As of March 2014, Project Gutenberg claimed over 45,000 items in its collection.
