Junior Library Guild

Junior Library Guild, formerly the Junior Literary Guild, is a commercial book club devoted to juvenile literature. It was created in 1929 as one of the enterprises of the Literary Guild, an adult book club created in 1927 by Samuel W. Craig and Harold K. Guinzburg. Book clubs often marketed books to libraries as well, and by the 1950s the majority of the Junior Literary Guild's sales were to libraries. In 1988, the name was changed to the Junior Library Guild to reflect this change in the company's business.

The Junior Library Guild is operated by Media Source Inc., which is based in Plain City, Ohio. The editorial department is in New York City.
