Found this at Teleread.org
CollegeDegree.com has a fascinating article by Kelly Kilpatrick listing, with links, 100 university libraries that anyone can visit on line. It starts with Harvard and Yale and finishes with the University of Zurich and the National University of Singapore Libraries. Take a look and bookmark it for future reference (pun?). Thanks to
bookofjoe.com for the post that put me onto this.
