This document discusses different conventions for digipak album packaging. It describes three common digipak styles: a 6-panel style with the album cover on the front and song list on an inner panel, with the CD in the middle panel; a 4-panel style also with the album cover prominently displayed and the CD on an outer side panel; and a 10-panel "X-style" digipak often used for compilation albums, displaying various artists on inner panels and keeping design simple with the CD centrally located.
