The annual Institute of Museum and Library Services Public Libraries Survey (PLS) contains 102 questions that all US public libraries complete. However, most states ask additional questions as well. The topics of these questions have been of great interest to public library data stakeholders for a variety of reasons, including that they may be the first indicators of new trends.
