It has over 300 computers for use by the public, an 8,140-square-foot (756 m2) atrium, an 18,560-square-foot (1,724 m2) green roof planted with low-growing ground cover designed to "be sun- and drought-resistant", and a host of energy-efficiency measures.
The Minneapolis Public Library and Information Center (MPLIC), opened on January 28, 1961 at 4th St. and Nicollet Ave. (the site of the current building).
[3] The building included a library, as well as a planetarium, auditorium, and a small museum in its basement which became famous to school children for its Egyptian mummies.
The new location in the then run-down "lower loop" district made the library a "cornerstone" of the 1960 redevelopment of downtown Minneapolis.
The Minneapolis Planetarium Society was at the second MPLIC building using a projector machine literally older than the space age itself (delivered and installed originally in 1954, three years before the launch of Sputnik I).
