After an Italian re-release in 1975, the single was not re-released on vinyl until 2012 (with the exception of a counterfeit, i.e. an illegal reproduction, in 1998).
Nearly 30 years after the original release, Ultima Thule, Part One was re-released on an official TD album (Antique Dreams, 2000) for the first time.
In 2004 the single was released as 5-inch CD as part of the Japan-only re-release of Alpha Centauri.
Exclusively for the Record Store Day (on April 21st, 2012) Esoteric released two limited edition vinyl items -- available from local independent record shops in the UK on that day only. Besides an LP re-release of Electronic Meditation, Ultima Thule was re-relased as 7" vinyl single in a cardboard sleeve.
