If you are a PI on an NIH grant, citations for publications that are linked to your grant can get automatically imported into your My Bibliography. This allows for easier management of publications as products in eRA Commons, which is linked to the My Bibliography.

When a publication gets linked, a light yellow banner will appear at the top of your "My Bibliography" saying that "# citation(s) have been linked to your funding and added to your bibliography". It is good practice to review these when they get added to ensure that publications did not get linked to your grant by accident or error.
