In Dungeons & Dragons (the '80s cartoon!), I heartily recommend the astounding Dungeons & Dragons cartoon encyclopedia! It's everything I ever wanted to do for FK non-fiction, and more and better. If you ever loved this show, it's easy to get lost in delight there, link to link, script to script.
In Battlestar Galactica (the original series!), I rely on The Battlestar Wiki for anything I can't remember where to find in canon (and for what's beyond canon). It has a few blind spots, connected (I presume) to certain Real Life situations (e.g. Serina isn't in the recurring character list, though several less-frequent characters are).
As you probably know, in Forever Knight, I assembled my own reference materials back in the day, including a script-based flashback timeline (a variation on wiliqueen's phenomenal costume-based flashback timeline, and building also on Dorothy's version), a Crusades/FK chronology alignment, and 7 character FAQs (mainly the S3 characters). I started, but never completed, lists of all named FK places and things and FK characters, and an FK quotation concordance. To this day, I keep print-outs of my timeline and aired-order episode list on a bulletin board above my desk at home.
