Between 2016 and 2019, Europe PMC increased its user base by about 39% (unique IP addresses per year). In 2020, this increase went up by 300%. API usage reached an all-time high in March 2021, serving 11M MB (11 TB) of data, over 20 times what it served in April 2016.
More specific milestones include:
· Europe PMC services have been more reliable and faster overall for the duration of 2016-2021 than in any other period of its operation.

· Since 2018, over 265K preprints have been included from multiple sources.
· 10M publications in Europe PMC are linked to at least one ORCID; this feeds the automatically generated Author Profile pages; the Europe PMC ORCID-claiming tool is still used by around 3000 unique users per month.
· The Scilite application visualises 1.3 billion bioentities, extracted by several contributors, and shared for reuse via the Annotations API
· 1.9M publications within Europe PMC are linked to data and integrated with BioStudies; all data are now easily findable through a single API call.
· The manuscript submission system was completely replaced through an open source software solution, developed together with Hindawi, eLife and the CoKo foundation.
· A major website redesign in 2019 merged the abstracts and full text pages and made it easier to find related information.
· The Europe PMC outreach program has reached over 40,000 people between 2016-2021. Europe PMC has been represented at over 150 events, provided training for over 10,000 users, and expanded its collaborations to include over 60 new data providers.
