Introduction
The Immune Epitope Database and Analysis Resource (IEDB) is a public repository of immune epitope data and is sponsored by the National Institute for Allergy and Infectious Diseases (NIAID).  The IEDB development started in December 2003 and it became available to the public in a beta test phase on 15 February 2006.  The IEDB contains data related to antibody and T cell epitopes for humans, non-human primates, rodents, and other animal species.  The IEDB also makes available a variety of analytical and epitope prediction tools and resources within its Analysis Resource.  Since its initial release, the IEDB functionality has been incrementally improved and enhanced.  A major redesign of the underlying data schema and the web interface was released in January 2009 and was designated IEDB 2.0.  Several updates have been deployed since that time.  This document described the features of IEDB Release 2.9 as of August 2010.
