Informatics On Biologists: Author Affiliations

As long as informatics on biologists counts as "bioinformatics", I hope this question can find an answer here...

I am trying to build a co-author graph based on institutional affiliations. I have a list of authors (or even a list of pubmed IDs) and thought I'd simply go to Pubmed and extract affiliation data from their xml return. BUT, to my surprise, they only provide the affiliation for the first author. What am I missing? What other sources do folks use for author affiliation data?

This doesn't help solve your problem, but NCBI recently announced that they will be changing this practice and will index all author affiliations submitted by publishers.

You're right, Pubmed only contains the affiliation for the 1st author. You can always get this information from the XML dump of the articles in PMC:

e.g: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=pmc&id=114965

   <contrib contrib-type="author">
          <name>
            <surname>Poncet</surname>
            <given-names>Didier</given-names>
          </name>
          <xref ref-type="aff" rid="N0x97cf288.0x8bf6180">2</xref>
        </contrib>

(...)

 <aff id="N0x97cf288.0x8bf6180"> Laboratoire de Virologie, H&#xF4;pital Armand Trousseau (EA 2391, UFR Saint-Antoine), Paris,<sup>1</sup> and  Unit&#xE9; INRA 1144 Virologie Mol&#xE9;culaire et Cellulaire, 78852 Jouy-en-Josas,<sup>2</sup> France</aff>

but beware: you cannot dump a large number of articles from PMC.
