"The Library is where electronic versions of classic books about individual liberty are stored. These texts go back some 4,000 years and cover the disciplines of economics, history, law, literature, philosophy, political theory, religion, war and peace. They are in a variety of formats - facsimile PDFs so scholars can view the original text, HTML for ease of searching and attractive layout, and text-based PDF EBooks for personal use. The Library also contains bibliographic information about the books as well as other "metadata" about the authors and editors. "
