Regular users of PubMed will have noticed a link on the homepage to the new redesign of the database. This redesign will co-exist with the old version for about two weeks before switching over completely. All search capability and functionality has been retained but the site has been given a fresh new look. For example the features of the Limits, Preview/Index, History and Details tabs have been consolidated into the Advanced Search. Display formats have been modified and updated.
