We use the "current listing with short descriptions" (it's only 9 pages long) on presscoins.com and cross out the ones we already have. We only take the pages that are pertinent to the park or hotel we are going to - in fact we cut it apart and put each section (such as Fantasyland, Adventureland, World Showcase, Future World, etc) in zip lock bags with the correct amount of coins (plus some additional in case of a bad printing) for that section.
We printed a second copy of that list that we keep whole and highlight those that we have and those that we get on the visit. This serves our master list. When there is an update, we use this one to repeat the process of identifying those that we have with new listing.
