Hi Edwin,

Thanks for your response. I appreciate your patience, and I'm sorry I
didn't get back to you earlier.

In response to your questions, there are fewer citations from the API than
exist in PubMed for the author's name for a given time period. The
precision of search is also very poor -- it's capturing only a handful of
articles with authors from our organization, despite the affiliation terms
in the strategy.  When we tested the strategy for the API, the precision is
very high. The automatic mapping in both versions shouldn't be an issue for
this search because all of our terms are tagged, but I was concerned that
either the differences between the interfaces or the ATM was causing issue.
I tested the strategy in both versions and they retrieve the same set and
the details show there isn't any automatic mapping being applied. I did
contact NLM about an API with new PubMed and unfortunately, they don't know
when a new version will be available for the new PubMed.
