The Graduate School and University Center of the City University of New York (known more commonly as the CUNY Graduate Center or the GC) is the main doctorate-granting institution of the City University of New York (while other CUNY schools may house doctoral degree programs, the degrees are granted through the GC). It is housed in the former B. Altman and Company department store on Fifth Avenue in Midtown Manhattan, which it shares with the Science, Industry and Business (SIBL) branch of the New York Public Library and Oxford University Press. The 4,000 students at the GC are mostly doctoral students in one of over 30 programs with the exception of those pursuing degrees in six master's programs and the CUNY Baccalaureate Program. The facility also houses the production studios and offices of CUNY TV, the University's 24/7 Educational-access television cable TV channel. The GC sponsors numerous continuing education programs, all open to the public, including regular lectures from world-renowned scholars, politicians and artists.
