Main Library, which opened in 1970, is one of the main study hubs at Northwestern. The library gets its unique structure and radial shelving system from architect Walter Netsch’s geometric concept of field theory. No idea what that is? Watch this episode of The Daily’s From the Archives series to find out.

Correction: This video names Deering Library as the oldest library on campus, but Lunt Hall, established in 1894, predates Deering as the oldest library at Northwestern. Lunt was the original sole home of Northwestern’s library, and houses the Math Library to this day. The Daily regrets the error.
