Worlds of Infinite Worlds

There are hundreds or more alternate worlds in the GURPS Infinite Worlds multiverse. Most of GURPS settings can be easily adopted as part of the Infinite Worlds settings which includes Infinity Unlimited. Note that GURPS 4e (2004) is not entirely consistent on how it uses the "^" (superscience) notation and "^" didn't exist in GURPS Classic at all. This coupled with changes in the GURPS TL scale means that TLs from sources before 2004 may not be at the same TL in 4e. A "map" of Known Realities can be hammered out based on Classic and 4e material.

==Additional information==
Timelines are listed by quantum. The number known is the number of timelines known to Homeline. Some timelines have moved quantum and a few even changed "local present" in 4th edition; those with only Classic sources are marked with "*". Tech Levels for uninhabited worlds are listed "NA". Due to the changes in Tech Level between Classic and 4e the TLs for 8+ from Classic material is not quite right. When possible the TL is updated to 4e (using the lowest TL possible) and in bold.
This topic is based on the lists formerly posted as Timeline Map for the Infinity Unlimited Campaign and Timeline Map, Infinite Worlds Wiki both of which are preserved thanks to Internet Archive. It is being updated to bring it in line with the GURPS 4th edition Infinite Worlds book and subsequent releases.
The number of realities for Classic (Homeline-2) and 4e is listed on the Known Realities page. Based on various details there are over 800 realities "known" with information on only about 220 of them.
Some additional details regarding some of these worlds can be found at uchronia.net.
==Important note on the years==
While the present for Homeline is roughly the same as ours (23-24 years from the relevant book's present and the same present as Merlin-1) most of the worlds haven't seen the relevant number of years pass for them (Alternate Worlds 1 and 2 still have Homeline's present at 2015).
For example, Cherokee is still in 1930 and Holly is still in 1989 despite Merlin-1 keeping up with our present. 
Three other issues are when Centrum discovered Homeline, when Homeline learned of Centrum; and Centrom-Beta which lost 15 years going from 1910 to 1895. These three things are the "smoking guns" confirming the Homelines of Classic and 4e are different though very similar.
One can easily hypothesize a Homeline-2 as representing the Homeline of Classic.
Worlds that have the same year in Classic and 4e are in bold.

===Quantum 5===
As Homeline is on Quantum 5, all transport to Quantum 5 is relatively cheap, as it does not require a projector. Thus, Quantum 5 worlds are particularly easy to trade with — and smuggle to. This fact, combined with mafiosos in Gallatin getting their hands on conveyors, means that just about anything can show up in the night markets and warehouses of Quantum 5 worlds, from goblin manuscripts to mammoth ivory.
