How UMLD Stores Books

The 12,000 square foot storage module can hold approximately 1.3 million items.   Five aisles, with two ranges each make up the present storage capacity of UMLD.  The stacks are approximately 30 feet tall.  Books on the high shelves are accessed by UMLD staff on a Raymond(R) narrow aisle heavy lift truck. Our “Raymond” is equipped with a safety basket which allows people to move about  at height with minimal risk.  A safety harness, along with wireless communication with the front offices, is also present.The climate in the storage module is maintained at a constant 55F at a relative humidity near 40%.  UMLD maintains a PI of approximately 120 years.  The controlled environment ensures that valuable, yet fragile, paper materials will be available for generations to come.
