5. Scope
Considerations
Build on PMC's role as
the repository for
NIH-funded peer-
reviewed articles
(2019)
Respond to
stakeholder need for
accelerated discovery
to COVID-19 literature
(2020)
Measured approach
to a new content type
to identify and resolve
workflow and data
challenges

Preprint v1 Preprint v2 Published article

14. Indexing a record
of versions.
Around 40% of the
preprint records in PMC
had been matched to a
published journal article
at the end of Q3.

15. Keeping current

16. Discovering
a record of
versions

17. PMC 1.5M
Preprint Page Views
PubMed 1.1M
Preprint Page Views

18. Increase each
quarter in authors
selecting NIH-

licenses.

20. Citing Preprints
Preprints in the pilot have been cited
~10k times
Two-thirds of those are citations of
preprints that have gone on to be
published in a journal

21. What's Next?
Continue to monitor
workflows for
scalability / pain points
01 02
Monitor Phase 1 impact
on discovery,
dissemination, & trust
03
Ongoing stakeholder
engagement

22. A record of versions
in a universe of
research objects.
