How can libraries best assess and improve user space, even if they are not in a position to undertake new construction or a major renovation? Staff at New Mexico State University used a variety of ethnographic methods to learn how our spaces were being used as well as what our users considered to be ideal library space. Our findings helped us make high-impact changes to public spaces while staying within a modest budget and a tight timeline. We used many of the same methods after our redesigns to evaluate our efforts and plan for future improvements. (Contains 10 figures.)
