University libraries often house collections of books that you don’t have access to unless you attend the school. But these days, thanks to the world of technology, many universities have opened their virtual doors and now allow everyone to view books and other materials online.
Harvard University offers an interesting variety of web-accessible collections , such as a collection of Chinese rubbings, digital scores and libretti from 18th and 19th composers such as J.S. Bach, and Mozart, and an extensive collection of maps.
At the Yale University website, you can search for information by author, topic or library. The Rare book and Manuscript library offers a fascinating collection of images, maps and manuscripts, and the Yale Daily News Historical Archive is just interesting to go through even if you have no specific information to find in one of their historical newspapers.
