The Bill Blass Public Catalog Room, also located in Room 315, is adjacent to the Main Reading Room, connecting it with the McGraw Rotunda.
The Catalog Room's central location between the McGraw Rotunda and Main Reading Room makes it a de facto foyer for the latter.
The room measures 81 by 77 feet (25 by 23 m).
Similar to the Main Reading Room, it has a 52-foot-high ceiling.
Four chandeliers, of identical design to those in the Main Reading Room, hang from the ceiling.
The ceiling of the Public Catalog Room also contains a 27-by-33-foot (8.2 by 10.1 m) section of James Wall Finn's 1911 mural.

Possibly the first renovation of the Catalog Room occurred in 1935, when its ceiling was repainted.
Further modifications occurred in 1952 when metal cabinets replaced the original oak cabinets as a result of the catalog room's quick expansion, with 150,000 new catalog cards being added each year.
The Catalog Room was restored in 1983 and renamed for Bill Blass in 1994.

There is an information desk on the north side on the room, on one's right side when entering from the rotunda.
Originally, visitors would receive card slips with numbers on them and then be directed to one of the Main Reading Room's halves based on their card number.
The Public Catalog Room also contains waist-high oak desks.
These desks contain computers that allow New York Public Library cardholders to search the library's catalog.
