For instance, around three quarters say that public libraries provide them with the resources they need. And 66% say the closing of their local public library would have a major impact on their community although notably, just 33% say this would have a major impact on them personally or on their family. A majority of Americans feel libraries are doing a good job of providing a safe place for people to hang out or spend time as well as opening up educational opportunities for people of all ages. And roughly half think that libraries contribute “a lot” to their communities in terms of helping spark creativity among young people and providing a trusted place for people to learn about new technologies. As in past Pew Research Center surveys of library use, the April 2016 survey also measured Americans’ usage of and engagement with libraries. Overall, 53% of Americans, age 16 and older, have had some interaction with a public library in the past year—either through an in-person visit or using a library website. Some 48% of adults specifically visited a library in the past 12 months, a modest increase from the 44% who said that in late 2015.
