Cambridge Digital Library. Newton Papers is a new online resource from Cambridge University. Cambridge University has the most extensive archive of Newton's manuscripts in the world. Although the current CDL offering is a small subset of the collection, more documents will be added as they are digitized. The scans of each item are in full color, cover to cover. Future offerings from Cambridge will include the works of Charles Darwin, Lord Kelvin, and other scientists. The collection is freely available online and easy to browse. Users may click on the title of a manuscript to view it in an interface that allows them to turn the pages. Users may skip to specific page numbers, but full-text searching is not available.
