There's an awful lot of useful, entertaining and authoritative web sites out there. The trick is to find them. LII, The Librarian's Index to the Internet, is a terrific search resource, and posts a weekly list of websites they have just added to their database, New This Week. This week's 'New', for example, includes links to Paleography, a tutorial about reading old handwriting, from the British National Archives (itself a great find); Ian's Shoelace Site, which includes the World's Fastest Shoelace Knot; a whole raft of fashion-related sites; and a brief History of the US Income Tax (sigh).
They have an email list you can sign up for, and an RSS feed. It's like the old days of URouLette, but with only the good stuff coming up on the wheel.
