[BioPython] Bio.EUtils, MultiDict: getting all the authors?

[richard k belew]

i am sure this has to have been addressed in a universe long ago and far
away, but...

i'm  trying to use Bio.EUtils to access NCBI/Entrez, but seem unable to
use its MultDict utilities as they are intended.

i include a sample run below.
i can contact NCBI and get the data just fine.  and the AuthorList = 
<OrderedMultiDict> is accessible.  the summary() whines about
finding "multiple Items named 'Author'!"

is there some (recursive?) idiom that is typically used?  i can
explicitly make the hack for extracting from the AuthorList, but
want to do something similar for any other OrderedMultiDicts, and
would like it all to stay as close to the DTDs as possible!

thanks for your help.
