Number of Libraries in the United States

ALA Library Fact Sheet 1

There are an estimated 119,487 libraries of all kinds in the United States today.

No single annual survey provides statistics on all types of libraries. Figures for public, academic, and school libraries come from surveys by the National Center for Education Statistics (NCES) and the Institute of Museum and Library Services (IMLS), while the others come from Information Today's American Library Directory.

Specifically, the public libraries numbers come from the IMLS Public Libraries in the United States Survey, from the latest report in the series, IMLS Public Library Survey FY2016. Retrieved from

The numbers for academic and school libraries come from the NCES Library Statistics Program and the Schools and Staffing Survey surveys, respectively: Academic Libraries: 2012 First Look (2014); Characteristics of Public Elementary and Secondary School Library Media Centers in the United States: Results From the 2011–12 Schools and Staffing Survey for the number of school libraries in public schools; Characteristics of Public and Bureau of Indian Education Elementary and Secondary School Library Media Centers in the United States: Results from the 2007-08 Schools and Staffing Survey for the number of school libraries in BIA (Bureau of Indian Affairs) schools; and Table 421. Selected statistics on school libraries/media centers, by control and level of school: 1999-2000 and 2003-04 from the 2008 Digest of Education Statistics for the number of school libraries in private schools (more recent library media center data for private schools have not been collected because of NCES budget constraints).

Figures for special libraries, armed forces libraries, and government libraries come from the American Library DirectoryTM 2015-2016, which is a two-volume set currently published by Information Today, Inc. now in its 68th edition

NOTE from American Library DirectoryTM 2011-2012 (page viii): "Branch records for academic and government libraries are no longer counted within these breakdowns, causing some discrepancy when comparing figures with previous editions. This does not affect the total number of libraries listed in the American Library DirectoryTM." Please contact Lauri Rimler at Information Today, Inc. with any questions regarding this. This difference was initially reported and took effect in the 2010-2011 edition.

For the purposes of ALA Library Fact Sheet 1, this counting difference actually most affected the American Library Directory's Total Special Libraries number; the 2009-2010 edition reported 8,906 Total Special Libraries, while the 2010-2011 edition reported 8,476 Total Special Libraries, the 2011-2012 edition reported 8,313 Total Special Libraries, the 2012-2013 edition reported 8,014 Total Special Libraries, the 2013-2014 edtion reported 7,616 Total Special Libraries, and the 2014-2015 edition reported 7,179 Total Special Libraries.
