Powerful system for collaboration: persistent linking, discoverability, trust

A standard way of reporting funding sources for published scholarly research

National Institutes of Health

NIH? N.I.H.? National Institute of Health?

Abbreviations, misspellings, translations...

Funding bodies cannot easily track the published output of funding

Publishers cannot easily report which articles result from research supported by specific funders or grants

Institutions cannot easily link funding received to published output

Lack of standard metadata for funding sources makes it difficult to analyse or data mine

Why does this matter?

Publishers

Relationship with authors submitting

manuscripts

Established publishing and peer-review

systems

Funders

Relationship with researchers funded by

agencies

Established award systems and research management processes

FundRef Registry

8,000 funder names and ID numbers from curated Elsevier SciVal registry, donated to FundRef

Hosted by CrossRef, available under CC0

Will be added to and updated

Publishers to use this list to ensure consistency
