Randall Munroe has been updating XKCD since late 2005 and has realized that he has been neglecting his collection by only adding to it. He has not spent time organizing his collected online works as their number expands.
Enter XSXKCD, pronounced "excess" or "access" XKCD. Munroe has hired us poor library school students to organize his collection. Our goal in designing XSXKCD is to keep those who frequent XKCD engaged so that they will continue to buy the prints, posters, and t-shirts that fund Munroe and our small operation.
