The National Library of Medicine recently made the following announcement about forthcoming changes to the PubMed interface:
Very soon a link on the PubMed homepage will connect to a preview version. The preview version will enable users to try out the new interface and is expected to run for at least two weeks after which PubMed will exist in the redesigned version. No changes to URLs will be necessary.
This change will affect PubMed @ Duquesne. If you have questions about searching the new interface, please contact David Nolfi, Health Sciences Librarian (nolfi@duq.edu, 412.396.4931).
