Study: How Americans Value Public Libraries in Their Communities.

At Pew's Internet & American Life Project:

Despite the fact that libraries are easily available to most, there are large numbers of Americans who say they are not sure about all the services libraries offer. Echoing the findings of our 2012 survey, 23% of those who have ever used a public library said they feel like they know all or most of the service and programs their library offers, while a plurality (47%) said that they know some of what it offers. About one in five (20%) say they don’t know very much about what is offered, and 10% say they know “nothing at all.”

I haven't read the whole thing yet, but wanted to pass along the link anyway!
