In 2008, we started by pulling a sample of 483 public libraries from across the country, using 2007 public library annual report data. Because small libraries have different needs and resources than larger libraries, we stratified the sample to make comparisons by size, according to the following population groups: fewer than 10,000 served; 10,000-24,999 served; 25,000-99,999 served; 100,000-499,999 served; and more than 500,000 served. [...] we plan to supplement future editions of the study with more in-depth investigation into particular libraries' deployment of certain technologies, taking a closer look at the role libraries play in maintaining a Facebook page, for example, and how patrons interact with the library through such forums.
