Overview
ISO 16439:2014 - Information and documentation - Methods and procedures for assessing the impact of libraries - provides internationally agreed terms, methods and procedures for assessing the impact and value of libraries. It supports strategic planning, internal quality management, benchmarking over time and between similar libraries, advocacy for libraries’ role in learning, research, education, culture and socio‑economic life, and evidence for political and funding decisions. The standard is applicable to all types of libraries worldwide, while noting that not every method suits every library.
Key topics and technical content
- Definitions and scope: establishes common terminology for library impact assessment (individual, institutional, societal impact).
- Types of evidence:
- Inferred evidence - e.g., statistics, performance indicators, user satisfaction data.
- Solicited evidence - e.g., impact surveys, interviews, focus groups, anecdotal and self‑assessment data.
- Observed evidence - e.g., observations, log analysis, citation analysis, testing of knowledge and skills.
- Method selection and combination: guidance on combining quantitative and qualitative data and on mixed‑method approaches to strengthen validity.
- Economic assessment: approaches for valuing library benefits, including consumer surplus, contingent valuation, cost–benefit analysis and broader economic impact analysis.
- Practical guidance: annexes with example impact surveys, advice on choosing methods, and how library impact assessment fits within wider institutional evaluation frameworks.
- Limitations and implementation: identifies challenges and constraints and provides guidance for planning and using impact assessment results.
Practical applications and who uses it
ISO 16439:2014 is used by:
- Library managers and staff - for strategic planning, service improvement, quality management and reporting.
- University and public library administrators - to benchmark performance and demonstrate institutional value.
- Policy makers and funders - to support resource allocation and policy decisions with standardized evidence of social, educational and economic impact.
- Researchers and evaluators - for designing robust impact studies using mixed methods and economic valuation techniques.
- Advocacy groups - to promote libraries’ contributions to learning, research, culture and local economies.
Practical uses include designing impact surveys, selecting appropriate performance indicators, conducting cost‑benefit or economic impact studies, combining qualitative stories with quantitative metrics, and comparing impact across similar libraries or over time.
