Although Marvel UK's Transformers primarily reprinted stories from the US series, it often featured original content usually written by legendary Transformers scribe Simon Furman. Thanks to the efforts of Titan Books, these stories are being reprinted in trade paperbacks and made available to many Americans for the first time. There's just one complication--while Titan's reprints of the US series are fairly sequential, the UK books reprint stories in a more thematic approach, collecting stories which were published months apart from one another. This makes keeping track of the reprints, and which comics still need to be reprinted difficult.

With a little digging I managed to compile a list of all 332 issues of the UK Transformers comic, noting which ones feature original content and, of those, which have been reprinted by Titan.
