Dear Colleague, If you have alerts set up in MEDLINE, please note the following message from Ovid, who supplies the MEDLINE database to the National Library for Health: Every year around this time, the National Library of Medicine (NLM) begins preparations towards a reload of its product MEDLINE. The duration of the reload phase usually depends on the nature of database changes being made. In past years there have been field changes (new fields being added or deleted, changes in data format, etc.) in addition to standard MeSH changes (usually consisting of deleting some terms, modifying term scope notes, and the addition of many new terms). Typically, we send out three emails detailing: the beginning of the process, a mid-way check-in, and a final approach signaling a firm date for when the database updates will begin anew. This year, primarily for internal reasons as well as the fact that few changes are being made to MEDLINE this year, we were unable to send out the first of the three messages in a timely fashion. The reload, which occurs annually, allows the NLM to update the controlled language MeSH(r) thesaurus and make other updates to the database fields. While this maintenance is being performed, no new records are added to MEDLINE. During the period of time that the NLM is finalizing its data, no updates are sent to any licensee, and thus MEDLINE is not updated until the reload is complete.
