The Minnesota Library Access Center is located 84 feet underground in a cavern 600 feet long, 70 feet wide, and 20 feet high.
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.
