There are some other revised omnibus editions out there, one of which is Diane Duane's Rihannsu: The Bloodwing Voyages from 2006...
The "Signature Edition" trade omnibus "Duty, Honor, Redemption" (Oct 2004) reprints the novelizations of "ST II: The Wrath of Khan", "ST III: The Search for Spock" and "ST IV: The Voyage Home" by Vonda N McIntyre had minor errors corrected, such as "McGivers" for "McGiver". Sulu's promotion to captain (in ST II) is removed, since the line was dropped from ST II and then ignored by the other movies.
"Pantheon" ("Signature Edition", Sept 2003) reprints "TNG: Reunion" and "TNG: The Valiant" by Michael Jan Friedman, with an all-new bridging arc that connects the two tales (ie. seven extra paragraphs from a reflective Guinan.) The bookend historical chapters for "The Valiant" are widened to embrace
both stories in the SE.
"The Q Continuum" ("Signature Edition", Oct 2003) reprints the TNG Q trilogy ("Q-Zone", "Q-Space" and "Q-Strike") by Greg Cox has several stardate error corrections, and changes a few mentions of "the original
Enterprise" to "Kirk's
Enterprise", to avoid confusion with Archer's ship (since "Star Trek: Enterprise" was the then-current series on the air).
The omnibus for the Reeves-Stevens' "DS9: Millennium" has a bonus Allyn Gibson timeline (of the complex plots) that didn't appear in the original MMPBs.
The MMPB omnibus collecting Michael Jan Friedman's "Starfleet: Year One", which was originally serialized over a whole year, has new material and new characters. Its original chapters were divided up and blended with each other, too.
Although some early promotional fliers for "Odyssey", the omnibus collecting the first three Shatner/Reeves-Stevens novels about Kirk, claimed it would have new linking paragraphs, the final result did not seem to include any new material.
The UK and Australian versions of the "Star Trek: The Motion Picture" novelization have extra sentences in several places, better describing the relationship between Kirk and Vice-Admiral Lori Ciana. They also contain a generous section of captioned colour plates: publicity pics for the movie. The US Pocket slipcased hardcover has a dedication "To Majel".
The MMPB version of the "Generations" novelization features the as-screened Kirk death scene, revised by Dillard herself. The original hardcover has the scene as featured in the bonus scenes of the DVD.
Oh yeah, and of course David Mack's standalone MMPB novel version of "Mirror Universe: The Sorrows of Empire" doubles the length of the original novella.
