The Internet Archive has just released a short video, Libraries Going Open, about the goals and progress of the Open Content Alliance (OCA).

The Open Content Alliance "represents the collaborative efforts of a group of cultural, technology, nonprofit, and governmental organzations from around the world that will help build a permanent archive of multilingual digitized text and multimedia content." The project focuses on public domain works that can be made freely available online.

The University of California Libraries are a major contributor to the OCA efforts. As of today, the UC Libraries have contributed 106,132 items to the Text Archive - including many classic texts in mathematics. Books can be read in PDF or Flip Book (example), among other formats.

Contributed books include:

• A course of pure mathematics (1921)
• Journal of researches into the natural history and geology of the countries visited during the voyage of H.M.S. Beagle round the world (1898)
• Newton's Principia: the mathematical principles of natural philosophy (1846)
• The principles of chemistry (1897)
• A short course on differential equations (1907)
  
• A treatise on electricity and magnetism (1873)
