http://www.sbirworld.com/
This is a cross-agency website that contains lots of information about SBIR & STTR Programs, conferences, solicitations, federal agency links, state resources, partnering, and news. The solicitations link at http://www.sbirworld.com/solicitations/solicitations.asp?mnuSol=1 is very good. There is also an "Open Solicitation" Search tool that works very well for all/any words or phrase and will search all or any selected agency. This website also has state resources and partnership lists.
