GovEvents
GovEvents is the premiere online resource for government events. GovEvents was created as a service to the government community so that government users, vendors, and event producers can go to one place on the web to find and post government-related events. The site provides in-depth information on hundreds of events, from major industry tradeshows, to government conferences, to agency-sponsored roundtables, and webcasts. Access to GovEvents is free of charge for all government users, event organizers and vendors/exhibitors.
