BYG Book & Record is the very first record album of School and the Backyard Gang material ever released. It was recorded in April 1963, at the end of the show's first season,[1] and was released later that summer.[2] The album was originally packaged in a gatefold sleeve that contained a full-color poster and a 24-page book featuring illustrations by Brian Cranner, as well as lyrics to all of the songs. It was also released simultaneously in a less expensive edition with a different cover, no book, and no poster. The songs from this album were also released on nine consecutively numbered 45-rpm, 7-inch records. The first six of these were also available in a "Carry About" boxed set, and the final three were also available as a set.

The album peaked at #23 on Billboard's Top LP's chart in 1963, and was certified Gold (sales of 500,000 copies) by the RIAA. It also won a Grammy Award for Best Recording for Children. It was subsequently reissued many times (without the book or poster), first on Columbia under several different titles and covers, then on other labels (see below for details). It was also later issued as part of the 1977 2-LP set Sesame Street Gold!

The entire album was released on CD for the first time under the title The BYG Record,
