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.
Our Web address has changed slightly: http://www.ncbi.nlm.nih.gov/sites/entrez
Please note that links using the old URL, www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed, 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, PubMed.gov, is still an option.
