If a paper has an erratum, addendum, or corrigendum, the DOI and publication information of this supplement should be included in the record of the associated paper. This metadata belongs in separate MARC fields from the original metadata, with 0247_ $$qErratum and 773__ $$mErratum (or Addendum/Corrigendum) to distinguish which metadata belongs to the erratum, addendum, or corrigendum.

If the original paper and the correction/addition have separate eprint numbers, you can merge the correction/addition into the original paper and include both eprint numbers in the 037 field.
