If you were stranded on an island and could have only one website ‘with you’ this might be the one to have. This is a cool wicked site. Some of the authors included are: Einstein, Kepler, Galileo, Shakespeare, Newton Copernicus and Euclid. Per the homepage description:
“Over the last decade, a company called “Octavo” digitally photographed some of the world ’s great books from some of the greatest libraries. These books were photographed at very high resolution (in some cases at over 200 megabytes per page).
This site contains all of the books (about 400) that have been digitized to date. These range over a wide variety of topics and rarity. The books are presented so that the viewer can examine all the pages in medium to medium-high resolution.”
