It would have to be tie between the EF & Mimbari Factbooks.
EF - because I'm not running a strict B5 campaign (just a very B5-ish game) the EF book has a lot of very useful material on Earth etc rather than just B5 (which does not exist in my universe) and loads of ships which I can use.
Mimbari - there was so much new stuff I did not know; and now want to find a way to use!!
