In response to the growing interest in the availability of data associated with articles,
PMC is reviewing current practices around data and seeking feedback on how to best serve the
data needs of the research community.
As part of these efforts, the PMC policy statement on
supplementary data was recently updated to more clearly articulate the requirement
that any supplementary data (images, tables, video, or other documents / files) that are
associated with an article must be deposited in PMC with an article. The search filter “has
suppdata[filter]” can be used in PMC to discover records with associated supplementary
In addition to providing supplementary data with an article, NLM is also encouraging
journals and authors to make research data available in a public repository and include the
relevant data citation(s) in the paper. Guidance for PMC data providers on tagging data
citations is available in the Tagging
Guidelines. This guidance is based on the JATS4R recommendations on data citations.
Starting this month, the NIH Manuscript Submission (NIHMS) system will also accept deposits
of small datasets accompanying deposits of funded author manuscripts for inclusion of PMC.
(Guidance for authors is available in the NIHMS FAQ.)
If you have suggestions on future directions in data for PMC to consider, please let us
