An album cover is the front of the packaging of a commercially released audio recording product, or album. The term can refer to either the printed paperboard covers typically used to package sets of 10 in (25 cm) and 12 in (30 cm) 78-rpm records, single and sets of 12 in (30 cm) LPs, sets of 45 rpm records, or the front-facing panel of a CD package, and, increasingly, the primary image accompanying a digital download of the album, or of its individual tracks.
