The Integrated Library System (ILS) is composed of bibliographic records including inventoried items, and patron records including circulation data. The data is used in the daily operation of the library, including circulation, online public catalog, cataloging, acquisitions, collection development, processing, and serials control. This dataset represents the usage of inventoried items by active patrons. Per the California State Library definition, San Francisco Public Library defines active patrons as a) patrons with unexpired library cards and b) patrons who had circulation activity within the last three years.

R code and data for a landscape scan of data services at academic libraries. Original data is licensed CC By 4.0, data obtained from other sources is licensed according to the original licensing terms. R scripts are licensed under the BSD 3-clause license. 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.

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.

The Public Libraries data set aggregates individual library services and finance data to the town level. Public libraries provide free borrowing privileges and services to their patrons and receive financial support from local tax funds. Public libraries may be municipal, which are established by and administrative units of local government, or association, which are not units of town government but receive some public funding. Some towns are served by more than one public library. Library visits include all persons entering a library for any purpose, including persons attending meetings or activities and persons requiring no staff assistance. Circulation counts all library materials of all formats lent out for use outside the library, including renewals. Registered borrowers are all town residents to whom a library has issued membership. Reference questions counts all interactions in which library staff provide information, knowledge, or recommendations to patrons. Town tax appropriation indicates the funds allotted to the library's operation budget from the town. The Adjusted Equalized Net Grand List per Capita (AENGLC) measures town wealth based on property tax and income per capita.

The State Library of Oregon collects annual service measures, financial data, and other statistics from all legally-established public libraries in the state, as per Oregon Revised Statue 357.520 (Annual report). The data reporting period matches the state fiscal year (July 1 through June 30). This dataset includes all Oregon Public Library Statistical Report data from each year starting in FY2009-2010, and is updated annually. Reporting periods are identified as the year the report was submitted (i.e., FY2009-2010 data is identified as 2010 in the Year column).

University of Pittsburgh librarians at the Health Sciences Library System and the University Library System conducted an 18-question online survey to learn what roles other academic and health sciences libraries are playing at their institutions in providing services and support to their users regarding electronic lab notebooks (ELNs). The survey was administered via Qualtrics. Questions included self-identification of being a health sciences library, whether their university offers an enterprise ELN license, if so which one and when did they start offering it, involvement in the selection process, types of services provided, service utilization, library staff involvement and workload, and whether other units at the university provide support. Questions were a mix of multiple choice and free text. Survey logic was used so depending on their answers respondents did not see all questions.Participants were recruited from September 7, 2017 through October 6, 2017. An email message and reminder were targeted to numerous library listservs requesting participation from ONLY academic libraries, including those in the health sciences. The email also stated "The information gathered will be used in developing our service model, and we also expect to incorporate it into one or more presentations or articles for publication. Although we ask for information identifying your library/institution, it will only be used for data analysis purposes. No library/institution will be identified publicly or linked to any particular response." We therefore removed any identifying responses from the data response spreadsheet posted here. Q1 and Q9 were removed, and identifying information within Q10, Q13, and Q18 was redacted.The CSV file contains de-identifed survey responses (indicated as #####). We did not include incomplete data (surveys with the majority of questions unanswered) and those responses that did not meet inclusion criteria of an academic/medical library. Also included is a PDF of the survey questions. This data was described here: Iwema, C.L. and Ratajeski, M.A. (2018, May).

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.
