The Mathewson Automated Retrieval System at the UNR Knowledge Center is a robotic system that houses many of the older, low-use books, journals, and other materials. These materials were formerly shelved in the stacks in Getchell Library, Special Collections, the Business & Government Information Center, Life & Health Sciences Library, as well as in the off-site storage facility. This is a temperature-controlled, efficient space that enables us to have a lot more open spaces for study, work, and collaboration throughout the Knowledge Center. Book stacks take up an enormous amount of space, and MARS frees up a great deal of that space. The system provides quick access to these materials, when compared to other storage options.
