It has since been renamed from the Asch Building to the Brown Building, and it is now part of New York University.
Every March a commemoration is held in the street by the building, and a fire ladder is raised to the maximum height of the ladder that could not reach high enough to save the people who jumped.
If you explore the link I posted, you'll find photos of the ceremony through the years.
Thanks again - my brother got his MA in English Lit at NYU, and I've been in that neighborhood many times - but I did not know this. I figured there would be some sort of memorial there.
And would still be a deathtrap if it were to catch on fire again, IMHO, unless the sprinklers are a lot stronger than I suspect. (I spent a lot of time in that building in college. Lots of tiny, twisty, turny halls. They do have giant fire doors that can be rolled into position by anyone at any time, though.)
