So I've been working on something for a while, but first a little backstory.
In the Greyhawk community, one of the major resources is a file known as the Encyclopedia Greyhawkia. This was a PDF created by a guy named Jason Zavoda some years ago, that indexed every NPC, location, group, event - essentially every proper noun in Greyhawk, from every published source. It was a huge piece of work, and I found it quite handy for my Greyhawk work. In Planescape, there's been plenty of resources for finding information on a topic; this site's Planar Encyclopedia was and is a big one for me. But I never found something that really gave the same level of indexing to the original sources. So I decided to make one myself.
It's still a work in progress, admittedly. Right now, I only have 5 works indexed out of about 40 Planescape publications and who knows how many Dragon and Dungeon articles and works from other settings with heavy planar content. However, I thought I'd link what I have so far, just to see what the public reaction is, and see if anyone has any suggestions on it or whatnot. It should be fairly self-explanatory in format.
Anyway, here's the file: Planescape Full Index Any feedback would be appreciated.
I like the idea - even if it is grand in scope. I like those ones. 
XD
Just bumping this because, although I never finished it before, I've been somewhat bored recently and I've picked the project back up. I've added about 4 or 5 works since I let things drop off with it around April; it's up to 11 total, with Faces of Sigil in progress at the moment.
