Hayden Library Reinvention

High traffic library engineered to accommodate paradigm change.

The renovation and addition of the 1966 Hayden Library Tower will include: adding multiple points of access, with greater indoor-outdoor connection; dedicating space for community gatherings; breaking the library up into thematic neighborhoods to better facilitate navigation and research discovery; and removing 1 million books from Hayden’s shelves to maximize space for students to study, work and interact, as well as to spotlight exhibits and collections

Further plans to complement the building renovation and modernize the library’s services include developing a network of makerspaces, in which students and faculty can create everything from podcasts to 3-D printouts, and cultivating partnerships universitywide that leverage and enhance the library’s unique data research centers, such as the new Map and Geospatial Hub, the special collections, including the Sandra Day O’Connor memoirs and the Barry Goldwater letters.
