About Minnesota Library Storage (MLAC)

The Minnesota Library Access Center is a "building inside of a building." The wall on the right has been built to support the sandstone cavern walls. The foil-lined wall on the left is the outside of MLAC.

The Minnesota Library Access Center is our high-density storage facility for Minnesota libraries that stores and makes available important but little used books. Unlike a library which shelves items either by subject or alphabetically by title, MLAC shelves items by size. The goal is to shelve at the highest density possible to maximize space usage.

Capacity

  • Predicted capacity: 1.4 million volumes.
  • Current holdings : over 1,357,000 volumes (August 2009).

Space Allocation

  • 60% is reserved for the University of Minnesota, Twin Cities Campus Libraries.
  • 40% is for Minnesota's academic, public and governmental libraries.

Accessing the Collection

  • Because the facility's shelves are 17 feet tall, books are retrieved by trained staff on forklifts.
  • The collection is closed to the public. All items in MLAC are listed in MnCAT, the University of Minnesota's online catalog along with links to request retrieval.
