LP is a 12-inch 33 rpm vinyl disk, listed here up to 1985 only. CD is the successor to the LP, a long-form CD with usually 10 or more songs, listed here for original CD releases from 1981 to the present. Unreleased recordings are listed only where they definitely exist, based on documentation or known copies circulated among fans. Up to 1966, Australian releases are shown, and from 1967 only US and UK releases are regularly shown. Bee Gees records appeared in Europe from 1967 and most of the world from 1968.
Singles often vary.
This is not intended to be a comprehensive list of releases. The optional note includes mainly information on recorded versions, such as later or previous recordings, and for unreleased recordings, whether any version of the song was released. For important recordings of Gibb songs , the format is similar to featured recordings. Notes mention whether it is the first recording of the song and otherwise why it is listed. For more Gibb songs , the song listing is usually just title and writers.
