The Washington Research Library Consortium includes off-site storage facilities for nine university systems, providing shared resources and cost savings for these institutions to keep a vast collection of books and documents. The total facility consists of three modules that hold 2,000,000 volumes and 50,000 archival boxes. The controlled interior environment maintains a temperature of 60 degrees with 40 percent relative humidity to preserve the longevity of the materials. Equipped with high-bay shelving, each row has motion sensor lighting systems to save on energy costs.
