Keri Smith is a Canadian author, illustrator and conceptual artist. According to her website, "The main focus of [Smith's] work/research is on creating what the writer Umberto Eco called 'Open works', pieces that are completed by the reader/user." Most of her books encourage readers to expand their scopes of creativity, such as in Wreck This Journal, where she has readers do things to the book itself rather than having readers simply draw or color within the book's pages. Besides Wreck This Journal, her other bestsellers include Mess and This Is Not A Book. She has also written for How Magazine.

Smith is also a freelance illustrator and has worked for Random House, The Washington Post, The New York Times, and The Boston Globe, as well as for Ford Motor Company, Gallison/Mudpuppy Press and Hallmark. Until 2011, she gave lectures on various topics for schools and organizations across North America.
