The National Center for Biotechnology Information (NCBI) provides a wealth of information in the fields of medicine and biological sciences. Most people are familiar with PubMed and Medline Plus - searchable databases to the literature. But, this is only a small subset of the available resources.
You can easily reach NCBI from ER using the Featured Resource PubMed@USU button or by searching for PubMed in ER.
(You can also access NCBI directly at: http://www.ncbi.nlm.nih.gov/
From the PubMed homepage, change the database option to All Databases with no terms supplied and click Search.
What is returned from the All Databases search is an annotated list of the searchable database resources that are available. As can be seen, the familiar Literature resources are just a small fraction of the total.
The various database are interconnected, with the Gene database being the central resource. Most searches will begin in either PubMed with a jump to Gene or starting in Gene directly.
The rest of this guide will walk you through some common sample searches.
