Books like xkcd

xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. The comic's tagline describes it as "A webcomic of romance, sarcasm, math, and language". Munroe states on the comic's website that the name of the comic is not an initialism, but "just a word with no phonetic pronunciation".

The subject matter of the comic varies from statements on life and love to mathematical, programming, and scientific in-jokes. Some strips feature simple humor or pop-culture references. Although it has a cast of stick figures, the comic occasionally features landscapes, graphs, charts, and intricate mathematical patterns such as fractals. New cartoons are added three times a week, on Mondays, Wednesdays, and Fridays.
