There are multiple affiliated projects that provide additional content, including region- and language-specific works. Most releases are in the English language, but many non-English works are also available. The releases are available in plain text as well as other formats, such as HTML, PDF, EPUB, MOBI, and Plucker wherever possible. As of 3 October 2015, Project Gutenberg had reached 50,000 items in its collection of free eBooks. All files can be accessed for free under an open format layout, available on almost any computer. Most of the items in its collection are the full texts of books or individual stories in the public domain. Project Gutenberg ( PG) is a volunteer effort to digitize and archive cultural works, as well as to "encourage the creation and distribution of eBooks." It was founded in 1971 by American writer Michael S.
