Official Traveller Universe
The Official Traveller Universe (OTU) is comprised of materials published by licensees, although these may be decanonized or overwritten by later materials. The following section is presented in roughly chronological order to illustrate the evolution of the OTU data corpus over time.
Ongoing review and development of the OTU is being coordinated by the Traveller5 Sector Survey (T5SS), an effort driven by Marc Miller to stabilize, correct, and control the UWPs of the OTU so that there's a solid canon base of data for future reference. Feedback should be directed to: Citizens of the Imperium: T5SS Semi-Official Thread
Sectors of the Third Imperium
Old Expanses sector designed by Jim Cunningham and Gordon Sheridan. Portions of Old Expanses sector originally appeared in High Passage Magazine.
Reaver's Deep sector was designed by J. Andrew Keith. Portions of Reaver's Deep sector appeared in High Passage Magazine, and in Far Traveller Magazine. Additional data and adventures set in Reaver's Deep sector were published by Gamelords, Ltd.

Two subsectors of Trojan Reach sector were designed by Bob McWilliams and appear in Traveller Adventure 4, Leviathan, designed by Games Workshop, published by GDW.
The following 35 sectors were mapped in the Atlas of the Imperium: The Spinward Marches, Deneb, Corridor, Vland, Lishun, Antares, The Empty Quarter, Trojan Reach, Reft Sector, Gushemege, Dagudashaag, Core, Fornast, Ley Sector, Riftspan Reaches*, Verge, Ilelish, Zarushagar, Massila, Delphi, Glimmerdrift Reaches, Hlakhoi*, Ealiyasiyw*, Reaver's Deep, Daibei, Diaspora, Old Expanses, Hinterworlds, Staihaia'yo*, Iwahfuah*, Dark Nebula*, Magyar, Solomani Rim, Alpha Crucis, Spica*. The Atlas of the Imperium was designed by Marc W. Miller, with assistance from Leroy W. L. Guatney and John Harshman for star system names, and was published by GDW. (Sectors marked with * do not contain worlds of the Third Imperium.)
Corridor sector was further detailed by Marc W. Miller in The Short Adventures - Memory Alpha, published by FFE.
Several sectors were further detailed in issues of The Travellers' Digest published by DGP, by James Holden and other authors. These include: Deneb (James Holden, Mike Mikesh, and Nancy Parker, #1, #2, #19), Corridor (James Holden, Phillip Athans, Mike Mikesh, and David Riddell, #3, #18), Vland (Nancy Parker and J. Andrew Keith, #4, #5), Lishun (#6, #7), Core (#8, #9, #10), Massilia (Nancy Parker and Robert Parker, #11), Old Expanses (Nancy Parker and Robert Parker, #12), Magyar (#14), Daibei (#15), Reaver's Deep (#16), Dark Nebula (#17), Ealiyasiyw (James Holden, #18), Riftspan Reaches (James Holden, #19), Trojan Reach (James Holden, Mike Jackson, and Clay Bush, #20), Reft (James Holden, John Meyers, and Michael R.

Note that only the details in FFE's document are used on the map. Additional details from Imperial Lines such as the borders of the Mnemosyne Principality and Avalar Consulate and the worlds Hollis and Raschev are now considered apocryphal, to allow for maximum creativity by other authors.
Many publishers and creative individuals have developed their own version of Foreven. Here are a few:
The Judges Guild published four approved sector supplements "Approved For Use With Traveller" by GDW, comprising what was called the Gateway Quadrant: Ley Sector, Maranatha-Alkahest, Glimmerdrift Reaches and Crucis Margin. While the names and locations of three of the sectors were retained for the OTU, most of the data was replaced by later publications. The Judges Guild versions of these sectors can be found on the Traveller Apocrypha II collection by Far Future Enterprises, as well as on the map, located far away from charted space: Ley (Judges Guild), Glimmerdrift Reaches (Judges Guild), Crucis Margin (Judges Guild), Maranatha-Alkahest

Borders and Routes
Where possible, polity borders and communication/trade routes shown on maps in previous publications have been used. Unlike the raw system data, there is no standard data format for representing these. Where not previously available, borders have been automatically generated - see Improved Automatic Border Generation for TRAVELLER Sectors.
