Drum Tower? There is Nanjing Library near the Drum Tower, which can be reached by bus No.95 or subway line 2 from the Drum Tower.

There is also the reading room in Gulou District, which seems to be on the west side of Shanxi Road Station on Zhongshan North Road, and in the same place as the basement.

There are not many books, but it seems that many mothers take their children to read them on weekends.
