The world’s classiest study hall is reopening soon, well ahead of schedule.

After being closed for more than two years for important repairs and restoration, the Grand Central of reading rooms at the New York Public Library’s “Ghostbusters” branch (Fifth Avenue and 42nd Street) is back to being a sanctuary for learning on Wednesday, Oct. 5 at 10 a.m.

The historic Rose Main Reading Room, which spans two city blocks, has been closed for over two years after one of the plaster rosettes fell from its ornate ceiling (while the library was closed) in May 2014. Hey, if you’d been built in 1911, things would probably fall off you occasionally, too.

The $12 million restoration was completed several months early, according to the library. Improvements include a massive new storage room under Bryant Park, an updated conveyor system to bring any requested research materials to the reading room, and in a move that hopefully won’t harsh the aesthetic of the grand space, the chandeliers’ lights have been upgraded to LEDs.

If you don’t have any pressing research projects, you can check out the reading room on the tours of the building at 11 a.m. and 2 p.m. daily, or find out more about the renovation with Preserving a Masterpiece, a free exhibit on the library’s third floor open through Oct. 9.
