Changes Coming to Author Affiliations in MEDLINE/PubMed
Beginning October 1, 2013, NLM will cease editing the Author Affiliation field in MEDLINE/PubMed citations. In the past, NLM policy was to carry affiliation for the first author only, quality control the data, and edit the field to add “USA” or e-mail address as appropriate. However, starting with the 2014 PubMed system in mid-December 2013, NLM will implement a new policy that allows publishers submitting XML citation data for MEDLINE indexed journals to submit Author Affiliations for each Author name, Investigator name or Corporate Author name.
To prepare for and support this change, NLM will cease quality control review and editing of the author affiliation field in the MEDLINE citation. Searchers who were using a PubMed search to limit to US authors as the first author should be aware that it will no longer be comprehensive as of October 1, 2013.
