When compact discs first began to appear in the retail stores, the longbox packaging served a transitional purpose, allowing shops to file new compact discs in the same bins originally used for vinyl records. Longboxes were 12 inches (30 cm) tall (the same length as the standard 33⅓ LP), and capable of containing two separate discs when necessary. Most longboxes were full color, with details about the compact disc on the back, and artwork that was frequently taken from the original square album cover art, reworked for the new shape and size.
