Public Libraries Survey Preliminary Data
The State Library participates in the national Public Libraries Survey (PLS), which is administered annually by the Institute of Museum and Library Services (IMLS). Data submitted to the PLS goes through a vetting process to ensure accuracy. Preliminary data is returned to the states annually, but is not considered finalized until published by IMLS. Not all data elements collected through the IPLAR are reported as part of the PLS.
The PLS also does not include data for libraries that do not meet the federal definition of a public library. Therefore, some Illinois libraries are not included in this data set. The 2015 PLS preliminary data is now available.
PLS Published Data
Public Libraries in the United States Survey, which is published online, provides a national-level analysis of the PLS that aggregates data from all 50 states and the District of Columbia to provide national estimates and trends. Public library data files (public use) are also released by IMLS for each fiscal year, and made available on their website.
Additionally, key information from the FY 2014 PLS on more than 9,000 public library systems and over 17,000 public library outlets is available through various data visualization tools provided on the IMLS Find Your Library website.
