PubMed retrieval glitches - Fixed

Update Tues 19th December - the problem is fixed.

Original post: Today (sic 18th Dec) we have noticed frequent glitches when we try to access records at PubMed. When you have done a search and want either to view more details or change the view for records, then the following error message is appearing:
"id: ######## Error occurred: Document retrieval error: document does not exist".

The id number is unique to each entry in PubMed so in place of ######## there will be an eight digit number.

The library has reported problem to PubMed.
