Ovid Technologies, Inc.Ovid MEDLINE®, MEDLINE® In-Process & Other Non-Indexed Citations, and Ovid OLDMEDLINE® Reload News |
The Ovid MEDLINE® databas has been reloaded. The reload includes updated MeSH tree terms for 2008. A complete description of the 2008 MeSH thesaurus changes are available from the NLM. In addition, MEDLINE® In-Process & Other Non-Indexed Citations (PREM) is now a segment of Ovid MEDLINE®. The MEDLINE® In-Process & Other Non-Indexed Citations (PREM) records are not completed Medline records, as such the MeSH terms will not be associated with records.
In addition, Ovid has made the following changes to the database:
