Ovid Technologies, Inc.Ovid MEDLINE®, MEDLINE® In-Process & Other Non-Indexed Citations, and Ovid OLDMEDLINE® Reload News |
The Ovid MEDLINE®, MEDLINE® In-Process & Other Non-Indexed Citations, and Ovid OLDMEDLINE® databases have been reloaded. These reloads include the 2007 edition of MeSH® (Medical Subject Headings) from the National Library of Medicine. A complete description of the 2007 MeSH thesaurus changes are available from the NLM.
Other changes include improvements to the presentation of MeSH and Scope Note data. Previously, some references were duplicated in some scope notes. These duplications have been removed.
With this reload, 72% of the OLDMEDLINE citations have had all of their keywords mapped to the current MeSH. These records will be designated as MEDLINE records and loaded into the MED1 segment. The remaining 28% of OLDMEDLINE records remain in the Ovid OLDMEDLINE® segment. We are also pleased to announce that the Ovid OLDMEDLINE segment has been loaded as a standard Ovid Medline segment, enabling articles for linking and tool functionality.
In addition, Ovid has made the following changes to the database:
