VIReC produces Research User Guides on select VA data sources to assist researchers in using VA data and information systems. These guides provide descriptions of variables, dataset names, data quality and historical information, access methods, and select bibliographies. VIReC Research User Guides are available from our Intranet site to researchers with VA network access.
