Ebooks@Adelaide
From the University of Adelaide, Australia. This site contains a large and growing selection of public domain ebooks. While these titles could be found on a variety of other sites such as Project Gutenberg, Adelaide has reformatted the titles to make them both easy to find an easy to read. Downloading is free, but can only be done one chapter at a time. NOTE: Due to the fact that Adelaide has chosen to embed the search engine in its Facebook page, navigation may be confusing.
