Answer

SHARES is a collaborative effort between a number of research libraries. In part, the program grants each participating institution's faculty, students, and staff on-site access to collections and services at other SHARES institutions.
 

Faculty, students, and professional staff at SHARES member institutions outside the New York metropolitan region are allowed reading privileges upon presentation of their valid school identification. Valid institutional ID must be presented at the Library Privileges service window to obtain a semester-long access pass.

Note: Faculty, students, and staff at SHARES institutions within the New York metropolitan area must provide a METRO referral card for access to Bobst, unless their institution is covered by a special agreement with NYU.
