Titan Books

In 2001, Titan Books acquired the rights to reprints of Marvel Comics' U.S. Transformers run, publishing the  complete near-complete American series in several volumes of trade paperbacks and hardcovers. They have also released much of the Marvel UK material.

Their sister company, Titan Magazines, is currently publishing a Transformers title based on the 2007 film.

Black & white
These compilations are listed in chronological order based on the first issue included, however the stories are bound by subject matter as opposed to sequential order.

Transformers: Fallen Star Collects: Stories from Marvel Transformers UK #215–218, #243–244, #248, #268, #270, #275-277 and #284–286 ISBN 1-84576-060-3

It was claimed that if they were successful they would finance future colour releases. Obviously this did not pan out. What is frustrating is that some stories (notably The Big Shutdown! and the Survivors saga), included within these volumes in black and white, had previously been reprinted within the original UK comics in colour.''

Non-Marvel collections
Transformers Adventures: (Vol. 1) Collects: Titan Transformers UK #1–? ISBN 1-84576-836-1 This has not been released yet so the exact contents are unknown.

Uncollected material

 * G.I. Joe and the Transformers #1–4 — Marvel U.S.'s 1986 crossover. This story did not take place in the UK continuity — at least not before the changes wrought by Time Wars.
 * Transformers Universe #1–4 — Marvel's character profiles.
 * Transformers Universe (various) — Character profiles printed as backups throughout the Marvel U.S. run.
 * "Man of Iron!", "The Enemy Within!", "Raiders of the Last Ark", "Decepticon Dam-Busters!", "The Wrath of Guardian!"/"The Wrath of Grimlock!", "Christmas Breaker!", "Crisis of Command!", "And There Shall Come...A Leader!", "Plague of the Insecticons", "To a Power Unknown!", "Ancient Relics!", "Peace" and "Destiny of the Dinobots!". It seems unlikely at this point that they will be reprinted, although a few of these were originally scheduled to be included in The Best of Simon Furman.
