Libraries are clearly in a state of transition, and library space is also being shaped by new librarian roles. As illustrated in this year's building project column, space is rapidly being redefined in new and exciting ways. In some cases, library space is being transformed into community spaces such as cafés, galleries, and exhibit areas; health sciences libraries are quickly catching up to public and academic libraries that have pioneered these types of facilities and services. In others, library space is being used to solidify partnerships between library staff and other academic personnel collectively working on projects, grants, or other strategic alliances. In these cases, space is leveraged to the library's advantage by inviting in partners who share similar goals and objectives. Sharing space allows experts from different backgrounds and disciplines to share their knowledge and develop collaborative projects. Clinical and Translational Science Award (CTSA) units and innovation centers are prime examples of these expert partnerships. Locating library staff adjacent to these experts has enabled them to share their knowledge and contribute to the shared projects as well. And finally, libraries can be spaces for discovery and creation of new knowledge in a much broader sense. They can be part of the larger learning or teaching center, providing study areas, test centers, laboratories, simulation centers, group collaboration facilities, and research evidence. Academic health sciences librarians and libraries need to remain agile as well as responsive to the needs of their organizations; for only then will they remain relevant.
