Finding Public Library Statistics
About Sources of Public Library Statistics
 Oregon Statistical Report  Oregon Statistical Report
The data collected by the Oregon Statistical Report encompasses all of the PLS (formerly FSCS) data elements, and includes some data collected at the state level.  It includes all legally established public library entities in Oregon.
Public Library Survey
Statistics are collected from 9,000+ public libraries, via the Public Library Survey (PLS), formerly the Federal State Cooperative System (FSCS). The states partner with the Institute of Museum and Library Services to coordinate and aggregate state statistical data on the national level. The aim is to survey the entire universe of public libraries. Data is checked for quality by State Library staff, and the U.S. Bureau of the Census.  There are entities, such as Yachats Public Library, and the Library Information Network of Clackamas County, that do not meet the federal definition of a public library and are excluded from PLSC.  The Census also estimates data for libraries that don't report it, so there will be some differences between the Oregon Statistical Report and PLSC figures.
Hennen's American Public Library Ratings
Using data from the PLSC (formerly FSCS), Mr. Hennen's ratings of public libraries are published in the October issues of American Libraries.  Note that the ratings are dated with the year of the report, not the year of the data.  For instance, the 2004 ratings are based on 2001-2002 FSCS data. 
  LJ Index 
LJ Index was created as an alternative to the Hennen Index.  This index examines only service outputs, such as visits and circulation, and excludes resource inputs.  Data comes from the Public Library Statistical Cooperative.  The LJ Index uses four per capita ratios that correlate with each other.

PLDS - Public Library Data Service Statistical Report
The PLDS is collected by the Public Library Association and contains data from nearly 2,000 public libraries. Each year the survey includes a special survey highlighting one service area or topic. The survey includes a random sample of 489 libraries serving populations 5,001-50,000. For 2012 and onwards, the data is accessible in an online database. Contact Susan Westin at 503-378-5435 or susan.b.westin@state.or.us for login information. The data sample is skewed towards larger libraries. Note that the year of the report is not the year the data were collected. The data sample is skewed towards larger libraries. Note that the year of the report is not the year the data were collected.

Public Libraries & the Internet
Since 1994, Drs. Bertot and McClure of Florida State University have conducted studies roughly every two years that track the level of involvement, key issues, trends, and other aspects of public library internet use. The survey covers issues such as internet connectivity bandwidth, internet-based service and resource availability, filtering of internet-based content and services, and costs and issues associated with internet connectivity. This survey is done on a sampling basis.
