Public libraries have a long history of adapting to meet the changing needs of their communities. This practice continues today, with libraries adapting their programing, material collections, and staff training to meets community needs. On March 30, 2017, the John S. and James L. Knight Foundation published this report outlining the "state of innovation capability and culture of urban public libraries." In collaboration with an outside consultant, the foundation interviewed numerous directors of urban public libraries across the United States in order to identify common challenges faced by library professionals in 2017. The results of this interview are outlined in the second section of the report, The State of the Field. This section also highlights a number of examples of how library staff are developing innovative solutions and programs to meet these challenges. Meanwhile, the third and fourth sections of this report provide a framework designed to aid libraries in developing and assessing their own innovative strategies.
