The New Frontier Timeline  compiled by Keith R.A. DeCandido

Background information 
 The idea of a New Frontier anthology was first broached by Pocket editor John Ordover. Peter David, who until this point had been the only writer on the series, noted in the introduction to the anthology, that he was apprehensive about the idea of handing over "his" characters to other authors. 
 Ordover then sought out story ideas from Star Trek authors, after announcing the idea of the anthology at one of the regular lunches he organized. ()
 One of the few stipulations of the anthology was that the stories could not be set during the timeline of the series proper, to avoid affecting the ongoing story line (although David himself broke that rule with the final story, "A Little Getaway"). ("Introduction")
 When the story ideas began to arrive, David found his apprehension lessening as the pitches showed him "the breadth of interest that New Frontier had for its readers" and that the authors were genuinely interested in telling stories in this universe. ("Introduction")
 At the beginning of 2003, DeCandido, who was now assisting David in an editorial role (although only David would be credited on the cover), approached a number of other authors, including several veterans of the Strange New Worlds contests, to pitch further stories to fill gaps in the anthology. Because of the short time remaining to finish the anthology, these stories often meant the authors had to turn around their manuscripts in only a couple of weeks. ()
 Terri Osbourne's story was based on an idea from Peter David, to feature every character played by Suzie Plakson in a single tale. This became Selar only, after Paramount requested that K'Ehleyr be taken out. ()
