We divide corrections into those related to citations and references, and all other issues. Please treat them as indicated below.
For corrections other than citations and references, simply email your request to firstname.lastname@example.org. Be sure to identify the paper that has a problem in a unique way (DOI, journal reference, eprint number, report number or INSPIRE ID) and clearly explain what the problem is and how you suggest it should be resolved.
INSPIRE has a new, easier, method for handling Citation/Reference corrections. For more information, please see Reference Corrections
