Welcome to LinkOut

Created: ; Last Update: August 13, 2014.

LinkOut is a service that allows you to link directly from PubMed and other NCBI databases to a wide range of information and services extending beyond the NCBI systems. LinkOut aims to facilitate access to relevant online resources to extend, clarify, and supplement information found in the NCBI databases.

LinkOut provides access to a variety of relevant online resources, including full-text publications, biological databases, consumer health information, and research tools, directly from PubMed and other NCBI databases.

All links are specially assigned to specific citations and database records. When accessing a link through LinkOut, no additional searching will be necessary to access the relevant resource that has been linked to the citation or database record.

Links are supplied by LinkOut resource providers. LinkOut resource providers are responsible for supplying and maintaining their links. We work with the providers to minimize errors. Please report broken links to vog.hin.mln.ibcn@tuoknil for repair.

Information about LinkOut is also available on the LinkOut website.

For additional information about the various types of links found in NCBI databases, please see Databases in Entrez Help.
