Princeton University would be opening about one million public domain works from their library system in an attempt to make them accessible online in a searchable format. The Princeton University library system comprises of the Harvey S. Firestone Memorial Library and thirteen extraordinary libraries located around the campus.

The books being measured for the project are out-of-copyright works and so the part of the public domain. Once digitized, the books would be fully searchable by researchers and readers alike. With Google Book Search, users could be view the texts online, download them, or even print them for later reference.

The project is likely to be completed over a six year period.
