As of Finals week, you can add Uris to the list of places that will turn you away after an ID check.
This is the first time that admittance to Uris’ Watson Library has been restricted to only B School students. The upper floor, 2M, has been off-limits for undergrads since April 15, but now the entire library will be an Undergrad-free zone from May 3-May 17.
B School students have been complaining about this issue for quite some time, and in the most mature fashion possible. If undergrads need a book from the library, a librarian will get it for them. Comment away, readership.
