From the Perseus site (accessed 2005-07-25):
Perseus is an evolving digital library, engineering interactions through time, space, and language. Our primary goal is to bring a wide range of source materials to as large an audience as possible. We anticipate that greater accessibility to the sources for the study of the humanities will strengthen the quality of questions, lead to new avenues of research, and connect more people through the connection of ideas."
As of 2014, the number of Classics words in Perseus amounts to 69 million. The library also contains dictionaries, reference works, translations, and commentaries in other modern languages, such as Croatian, German, French and Italian.
In April 2013, the Perseus Digital Library joined forces with the Open_Greek_and_Latin#Description Open Greek and Latin project at the University of Leipzig.
