Research visual overlap

The following image was taken from an article titled "Teens and Information Literacy...and the Public Library written by Katie Day. The article was found through a Google search for research on teens in the library.

The article can be found here: http://librarianedge.pbworks.com/f/KDay_Teen_InfoLit_and_Libns.html

The author has done an extensive literature review to determine the role of the public library in the literacy development of teens. The image illustrates how school libraries have a greater impact on teen information literacy than do public libraries, yet the role of public libraries is not insignificant.
