[Bioperl-l] Bio::Biblio fails for "recent" publications

[Nicolas Thierry-Mieg]

Hello,

I have a script that uses Bio::Biblio to fetch publication data. This 
has been working for some time, but users reported last month that it 
now fails for recent publications.

For example:

This works (a publication from 2009):
perl -MBio::Biblio -e 'print new Bio::Biblio->get_by_id ("19147664")'

But this fails:
perl -MBio::Biblio -e 'print new Bio::Biblio->get_by_id ("21087995")'

The error message has:
Citation 21087995 was not found in MEDLINE/MEDLINENEW.

However that PMID does exist in pubmed:
http://www.ncbi.nlm.nih.gov/pubmed/21087995

I found that there have been recent changes at the NCBI, could my 
problem be related?

Any hints would be very welcome!

Regards,
Nicolas
