Through links to other resources at NCBI, such as PubMed, Gene, and OMIM, Bookshelf enables readers to discover relevant biomedical information (see Figure 1). A number of full-text books, reports and databases hosted in Bookshelf can be accessed through links in their corresponding entry in PubMed, a database of citations and abstracts for journal articles, books and documents (see the NLM Technical Bulletin for more information). PubMed and Bookshelf are also interlinked by 1) links in PubMed to publications in Bookshelf that have cited a PubMed citation in their bibliography, and 2) links to PubMed citations from articles cited in publications on Bookshelf.

AGRICOLA (AGRICultural OnLine Access) serves as the catalog and index to the collections of the National Agricultural Library, as well as a primary public source for world-wide access to agricultural information. The database covers materials in all formats and periods, including printed works from as far back as the 15th century.
