The library had a much larger 190,000 square foot addition built starting in 2003-designed by EHDD Architecture of San Francisco, CA.

[8] Recently labeled a "Smart Library" by Campus Technology magazine,[9] the Merrill–Cazier Library offers a technology-rich environment with radio frequency identification tags (RFID), a self check-out system, an on site automated retrieval system, the Information Commons consisting of 150 computer workstations, group study rooms of which 14 are equipped with computers and large screen LCD displays, two multimedia suites, and two library instruction rooms with over 60 workstations.

[10] An automated storage and retrieval system (ASRS) is an integral part of the building and allows for many years of collection development.

[11] Designed and built by Daifuku of America at its North American Headquarters in Salt Lake City, the system is enclosed in a 56-foot-wide (17 m) by 140-foot-long (43 m) and 80-foot-high (24 m) climate-controlled corner of the library building.

[12] The BARN (Borrower's Automated Retrieval Network) was so named in reference to Utah State University's status as an agricultural school.
