Choose a source for the question
Use the CORDIS project record for the grant identity and dates. Use the final report for the account of work completed. Use the paper for its specific research method, and the repository records for the supporting data and extended material. Those sources complement one another; they are not interchangeable confirmations of every claim.
Keep editions visible
When saving a reference, retain its author, title, identifier and version. A DOI ending in .3 identifies a different version from one ending in .1. An old website’s download label is not a substitute for that publication identity. Our source library keeps the trail explicit so a later reader can retrace it.
