Randall Munroe describes xkcd as a webcomic of romance, sarcasm, math,
and language. While it's practically required reading in the geek
community, xkcd fans are as varied as the comic's subject matter. This
book creates laughs from science jokes on one page to relationship humor
on another.
xkcd: volume 0 is the first book from the immensely popular webcomic
with a passionate readership (just Google xkcd meetup).
The artist selected personal and fan favorites from his first 600
comics. It was lovingly assembled from high-resolution original scans of
the comics (the mouseover text is discreetly included), and features a
lot of doodles, notes, and puzzles in the margins.
The book is published by Breadpig, which donates all of the publisher
profits from this book to Room to Read for promoting literacy in the
developing world.
