Good news for PubMed searchers!  Presently, the great majority of PubMed records contain the affiliation of the first author only.  Beginning in mid-December, 2013, for PubMed 2014, publishers will be able to submit author affiliations for each Author name, Investigator name or Corporate author name associated with records for inclusion in the database.  This advance will greatly assist in carrying out author searches.  The policy will apply to MEDLINE indexed journals.  There is a component of PubMed which contains records from non-MEDLINE indexed journals and the new policy will not apply to them.
