Like Paul says, the lean-tos in the catskills are marked on the TC maps. The only changes that I know of the location from my 1999 catskill maps to the latest is the leanto on Table has been moved from the Deer Shanty location across the infamous log bridge up high to just below the 3500' mark.
And the leanto on Long Pond by Mongaup was moved from the NW side of the lake to the SE side. (Although I don't know if this was a mistake on my 1999 map or the LT was moved, I just know the latest catskill maps shows it on the SE side.
The catskills maps don't list the legal campsites though.
The leantos in the ADKs are on my ADK guidebook map, they even list the number of campsites around the leanto too, whereas the TC catskill ones don't.
