LinkOut

LinkOut is a feature of Entrez that is designed to provide users with links from PubMed and other Entrez databases to a wide variety of relevant web-accessible online resources, including full-text publications, biological databases, consumer health information, research tools, and more.   (Examples of LinkOut resources)  The goal is to facilitate access to relevant online resources beyond the Entrez system to extend, clarify, or supplement information found in the Entrez databases.

Links to external resources are listed in the LinkOut Display of an Entrez record.  Users can access the LinkOut display by clicking "LinkOut" from the Links pull-down menu in all display formats .  The LinkOut display is also available from the display list of a record.  Please consult the Help document for additional information.

In PubMed, external resources can also be accessed through an icon from the Abstract and Citation formats.  Users can customize the LinkOut display and icon through the LinkOut Preferences in Cubby.

The Overview on the sidebar provides documentation on how to become a LinkOut provider and link your resources from PubMed and other Entrez databases, including information specific to publishers, libraries, and non-bibliographic resources.

If you know of online resources that might be valuable to Entrez users, make a suggestion to them to participate in LinkOut.
