Webcomics have been around for a long while, and that's raising a question: who's going to preserve those comics for online viewing outside of non-profits like the Internet Archive? The Library of Congress, that's who. It just launched a Webcomics Web Archive that curates stand-out strips. Many of them are award-winning or otherwise stand-out comics that you may have read -- the nerdiness of XKCD and the historical spoofs of Hark! A Vagrant are among the initial batch.
