  Greetings,

  I just started using the JSON version of the API. After retrieving a data set of few hundred publications (with 'memory' as the keyword), I noticed that all 'Affiliation' fields for the authors are 'null'.

  This did not change if the search criteria changed to more recent publications, or multiple authors, etc. Also, I searched other terms with similar results.

  Is someone seeing different results?
