More changes in PubMed

From this month PubMed is changing the order in which authors appear in its records to truly reflect that appearing on the published papers. This change particularly affects Corporate or Group authors.

To summarise how these authors have been handled in the past:
1966-1999 : Corporate author(s) placed at the end of article title, so need to search [ti] field to find them.
2000-Apr 2006: Corporate author(s) entered in separate field and always displayed last in the list of authors. Use field code [cn] to search for these.
May 2006 - : Corporate author(s) entered in separate field and displayed in the order found in the byline of the published article. Use field code [cn] to search for these.
