Wikisource is another project initiated by the Wikimedia Foundation, the same folks who created the popular Wikipedia. The Wikisource Project aims to bring together all kinds of public domain full-texts and even audio files. A good explanation of the scope of the project is found on their Community Portal Page. And, according to the latest information, there are now over 53 different languages represented. As a Wiki project, of course, it is user-generated, relatively unstructured and best approached in a spirit of exploration and discovery! The Main Page allows you to select from among all the languages.
