Foundation Center - Research Studies - Regional Trends
I always want to know the latest research published on my topic before I start writing an application. It helps inform the proposal - everything from the field's buzz words to the design of the program.
The Foundation Center's PubHub is a good place to start that research. It's a repository of reports created with foundation money, so you know the content reflects funders' agenda. You can search by subject, keyword, publisher, foundation - and a mix of all of these.
