Over the festive period, Ovid who manage NHS access to the Medline database on Search 2.0, take the opportunity to update and re-build the database. This may cause some periodical disruption to access.
Current slow operation and timing out issues have been reported to the appropriate people, and is currently under investigation.
Apologies for any inconvenience this may cause in the mean time.
Edit 6th January: Although the major issues have now been resolved, some intermittent problems may occur throughout January and no new articles will be added to the database during this time. PubMed remains unaffected. Alternative access to the full database is available via the Keele Ebsco access, which can be accessed through computers in the Health Library IT Suite.
