I recently decided to fill out parts of my FASA sourcebook collection and had to triage the catalog to determine what I considered essential for purchasing. The result is a companion piece to my
Modern Sourcebook Index by Era.
All items have been give an in-universe date (IU) except the original run of sourcebooks up through the first Periphery volume that all were set roughly in 3025 and TROs, which were set in the year on the cover (excepting 2750)
As always, corrections welcome. I'm a typo magnet.
