New and Improved PubMed®/Entrez and New URL

NCBI is changing to a new version of the Entrez system in a phased implementation beginning today. The new system offers more flexibility and will serve as the foundation for creating the next generation of features and capabilities for Entrez databases.

Users had a preview of the new system recently when a "Beta" version was made available. See NCBI to Introduce Changes to the Entrez System for a description of some of the changes that are included with the introduction of the new system.

We've Moved!

Our Web address has changed slightly:

Please note that links using the old URL,, will point to the new address and continue to work. New links should be created using the instructions found in Help, Creating a Web Link to the Entrez Databases.

Our easy address,, is still an option.
