The Lloyd Sealy Library serves the students, faculty, and staff of John Jay College of Criminal Justice.

John Jay College of Criminal Justice was established in 1964 and first opened its doors to enrolled police officers in 1965.

By the late 1960s, its collection was split between the Police Academy building, 360 Park Avenue South, and the top floor of the Strand Bookstore.

[1] In 1974, the Library consolidated its collection and moved to the college's new building, North Hall, located at West 59th St. and 10th Ave., under the leadership of Chief Librarian Carol Alexander.

As the building's interior was being designed, "the administration pressed from the start for the library to be its focal point" to emphasize the college's commitment to higher education.
