The Public Libraries Survey (PLS) is an annual survey of U.S. public libraries. Policymakers and practitioners depend on PLS data to allocate funding and strategically manage libraries. Academics rely on PLS data to conduct original research about public libraries. Data in the PLS come from over 17,000 outlets, and it represents a "gold standard" for national information about public libraries. While the PLS is an invaluable resource for the public library community, other organizations collect data that extends the reach and significance of the PLS. This dataset extends the PLS using information from the Public Library Association (PLA), the Association of Bookmobile and Outreach Services (ABOS), and the U.S. Census Bureau. PLA data comes from Project Outcome, a free toolkit and online resource for public libraries to document the outcomes associated with public library services. Since 2015, Project Outcome has collected more than 390,000 responses to surveys at 2,200+ libraries in the U.S. and Canada describing the outcomes resulting from library services. The standardized surveys used by Project Outcome have enabled libraries to aggregate their outcome data and analyze trends by topic, type, and program. ABOS data comes from a 2023 national, non-representative survey of public libraries regarding their outreach departments, services, and vehicles. Census data is from the American Community Survey and provides demographic information regarding the geographies that public libraries serve. As part of an Institute of Museum and Library Services grant, the Inter-university Consortium for Political and Social Research curated these data for reuse and mapped them to libraries in the PLS. The result is a combined dataset that documents the impact of library programming and outreach on nationwide communities. To enhance these data, a committee led by the University of Missouri, School of Information Science and Learning Technologies identified supplemental variables (e.g., Census demographic figures) and guided data curation by creating a "data module" specifying curation enhancements.

This dataset provides information on 18,791 in United States as of June, 2025. It includes details such as email addresses (where publicly available), phone numbers (where publicly available), and geocoded addresses. Explore market trends, identify potential business partners, and gain valuable insights into the industry. Download a complimentary sample of 10 records to see what's included.

This dataset contains aggregated data for fiscal years 2006-2020 from the Institute of Museum and Library Services' annual public library survey. This transformed version of the data contains aggregated data by material type for all public libraries in the nation, as well as an additional subset of the data for aggregated data by material type for Oklahoma's public libraries. Column headers include: Year, Print Materials, Electronic Materials, Other Materials, and Total. Material categories represent: material expenditures for physical materials (books, current serial subscriptions, government documents, and any other print acquisitions), electronic materials (ebooks, e-serials, government documents, databases, electronic files, reference tools, scores, maps, or pictures, including materials digitized by the library), and other materials (microform, audio, video, DVD, and new formats). These values were directly pulled from corresponding datasets for each public library from the PRMATEXP, ELMATEXP, and OTHMATEX columns, representing physical, electronic, and other material expenditures, respectively. Negative and zero values (-3, -1, 0) were excluded from categorical tallies, with -3 values representing closed or temporarily closed administrative entities. No explanation for -1 or 0 values was present in IMLS documentation. Valued were tallied by column after negative and zero values were excluded, with final tallies for each data column included in the attached dataset. Lastly, annually tallied were summed by each year in both National and State datasets. Two sets of the data are available: One set with two tabs (one each for National and State spending) in an Excel format, and two separate files (one each for National and State spending) in a CSV format.

Summary This work generally focuses on four questions:

Which research data services does an academic library provide? For a subset of those services, what form does the support come in? i.e. consulting, instruction, or web resources? Are there differences in support between three categories of services: data management, geospatial, and data science? How does library resourcing (i.e. salaries) affect the number of research data services?

Approach Using direct survey of web resources, we investigated the services offered at 25 Research 1 universities in the United States of America. Please refer to the included README.md files for more information.

A catalog of the holdings (i.e. books, documents, journals, etc) in all the EPA libraries. It is available to the public via epa.gov. In addition to being an online catalog, it also has modules that support the various operations of the libraries (circulation, serials management, dispersal tracking) that are only accessible by authorized users.

Context

Increasing numbers of public libraries are eliminating overdue fines for their patrons. The American Library Association passed a resolution in 2019 recognizing that the “imposition of monetary library fines creates a barrier to the provision of library and information services” (p. 2). Using data retrieved from both the Urban Libraries Council and End Library Fines in August 2019, we found that the number of libraries instituting fine-free policies has nearly doubled each year since 2015. How might such a policy change affect patrons, circulation, and library budgets?

Content

In January and February 2020, we submitted FOIA requests using MuckRock's platform to 52 public libraries who have eliminated fines in the United States. We requested information related to patrons, circulation, and budgets. The COVID-19 pandemic hindered our ability to retrieve data, but we were able to gather information from some of the libraries. This dataset contains total circulation data by month for 24 months pre-fine-elimination and 12 months post-fine-elimination for 16 public libraries in the U.S.

These datasets, clustered by library type, contain cleaned data survey results from the October 2021-January 2022 survey titled "The Impact of COVID-19 on Technical Services Units". This data was gathered from a Qualtrics survey, which was anonymized to prevent Qualtrics from gathering identifiable information from respondents. These specific iterations of data reflect the cleaning and standardization conducted on the raw dataset retrieved from survey responses, and then cluster the data into specific library type files. All files reflect the removal of data auto-generated by Qualtrics (such as survey start/stop times), blank rows, survey responses not completed after question four (the first section of survey questions), and non-United States responses. Survey respondents were asked to identify their library type (Academic, Public, K-12 School, Special Collections and/or Archives, Other, and Blank responses). There is some duplication between files, as respondents were allowed to select more than one library type to represent the sometimes complicated governing structure within libraries. Note that these files also contain an additional cleaning steps to standardize numbers within the "How many full and part-time staff members (not student workers) were on your Technical Services team prior to the COVID-19 pandemic?" and "How many full and part-time staff members (not student workers) are on your technical services team now?" questions (Q6 and Q7). String text was removed from these fields, as well as incomplete responses (e.g. Indicating a before number but not an after number).

The library patronage indicator measures the percentage of the total resident population served by each public library (the percentage of eligible residents that holds an unexpired library card). Ten public libraries and public library districts in Champaign County are included: the Champaign Public Library, the Homer Community Library, the Mahomet Public Library District, the Ogden Rose Public Library, the Philo Public Library District, the Rantoul Public Library, the St. Joseph Township-Swearingen Memorial Library, the Sidney Community Library, the Tolono Public Library District, and the Urbana Free Library. Public libraries often serve as community hubs and offer a number of educational and social opportunities and services for their population served. Registration for and maintenance of a library card is one way a resident can engage in recreation and other community involvement.

In 2021, five of the ten libraries analyzed had residential participation rates between 20 and 30 percent: Champaign Public Library, 27.57 percent; St. Joseph Township-Swearingen Memorial Library, 25.12 percent; Mahomet Public Library District, 22.38 percent; Tolono Public Library District, 21.82 percent; and the Philo Public Library District, 21.3 percent.

The libraries with the greatest percentage of the resident population with unexpired library cards were the Homer Community Library, at 38.96 percent, and the Urbana Free Library at 30 percent. The libraries with the smallest percentage of the resident population with unexpired library cards were the Sidney Community Library, 18.13 percent; Rantoul Public Library, 17.22 percent; and the Ogden Rose Public Library, at 13.85 percent.

All ten public libraries in Champaign County saw the percentage of their resident population with unexpired library cards decrease between 2015 and 2021. It is worth noting that many library buildings were closed during part of 2020 due to the COVID-19 pandemic, and that along with statewide stay-at-home orders may have deterred residents from renewing or obtaining library cards.

The release of the 2020 Census results in 2021 shows that the population in eight of the ten library districts decreased from 2010 to 2020. It is important to note that the population of a library district sometimes differs than the population of the municipality where it is located (e.g., Tolono).

The two library districts that saw a population increase in 2020 were the Champaign Public Library and Tolono Public Library District. However, the number of unexpired library cards in those districts decreased in 2021, so the decrease in the percentage of the population with library cards cannot be explained by population growth.

The two library districts that saw an increase in the percentage of the population with library cards from 2020 to 2021 are the Homer Community Library and Urbana Free Library. The number of unexpired library cards at the Homer Community Library increased from 2020 to 2021, which explains the percentage increase. However, the number of unexpired library cards at the Urbana Free Library decreased from 2020 to 2021, so the percentage increase is due to the library district’s population decrease.

Data was sourced from the Illinois Public Library Annual Report (IPLAR), an annual report from the Illinois State Library and Office of the Illinois Secretary of State. The population data included in the IPLAR dataset is sourced from the 2020 Census. To be consistent with the data source, we have also calculated the percentage of residents with library cards based on the number of cardholders divided by the total 2020 Census population.
