Libraries today have become centers of knowledge creation, and facilitate both collaborative learning and contemporary student culture.  The success of these spaces relies on the appropriate scale of space, an inherent flexibility that enables future adaptability, and allows users to feel a sense of ownership of the spaces they occupy.  The PDR team works almost exclusively on academic libraries, therefore we are intimately acquainted with the intricacies of 21st century library design, including collections management, services operations, and special collections.
