The document summarizes findings from a Pew Research Center survey on Americans' use and views of public libraries. It finds that 54% of Americans have used a public library in the past year, and 72% live in a household that uses the library. Most Americans say libraries are very important to their communities and would be impacted if their local library closed. While many value library services like books and assistance, awareness of all services offered varies, with some unaware of the full range.
