The framework is validated by using real data from HEAL-Link, the national consortium of Greek academic and research libraries to calculate the indicators. Design/methodology/approach – The paper reports on the related work regarding the services consortia offer to their members and the known methods and tools for assessing consortia services; the HEAL-Link case study, the aggregation and handling of data, is presented; ISO 11620 performance indicators for HEAL-Link services are calculated, and the results are discussed in terms of what was learnt- about the consortium, about measuring consortia services performance, and about the standard. Findings – ISO 11620 could be used to measure performance for assessing consortia services. The performance indicators’ results reflect the two major events (mergers and COVID pandemic) that took place during the time of the study. ISO 11620 offers a basic insight that could be well complemented with other tools and standards. Originality/value – The current study suggests that a widely accepted, easily applied, benchmarking ISO standard could be used to measure common consortia services’ performance, thus contributing to consortia assessment.
