Not too long ago, I stumbled across a nifty Website that was basically an index for nearly all comic trade collections; it told which collections were availble for which titles, and which issues those collections contained.
Alas, I seem to have neglected to bookmark the site, and my librarian super-powers are failing me in finding it again.
Does anyone know which site this is, and what its URL is?
Update: Never mind, I found it; it's at http://tplist.millarworld.net/index.html. (And reader/commenter Canton found it under an alternate URL.) I'll stick it in my del.icio.us links so I'll never lose it again!
