 The main story consisted of 11 parts running through the Green Lantern and Green Lantern Corps books. Expanding upon the overall story are four one-shots labeled Tales of the Sinestro Corps, as well as one tie-in with Blue Beetle # 20. Part One, the one-shot Green Lantern: Sinestro Corps Special # 1, was released in June 2007. Parts Two through Ten were released between August and December, alternating between Green Lantern # 21 – 25 and Green Lantern Corps # 14 – 18, with an epilogue in Green Lantern # 26. The content of Green Lantern Corps # 19 was changed to illustrate the battle between Sodam Yat and Superman-Prime in response to the fans' reaction to the story. Geoff Johns announced in October 2007 that the conclusion Green Lantern # 25 would be delayed two weeks. After the storyline concluded, Green Lantern / Sinestro Corps Secret Files # 1 was released in December. The issue further explored the back story of the opposing groups and listed every member of the Green Lantern Corps and Sinestro Corps.
