We have done the work for you to find websites that provide sources for corporate and foundation grants. One of the best websites listing resources on a variety of grants — government and private — is posted on About.com.

This Grantsmanship Center website holds the mother lode for a grantwriter. A map with clickable states takes you to lists of the following types of grantmakers in your state: top grantmaking foundations, community foundations, corporate giving programs and the homepage of every state government. The Center has paid subscriptions and other services that can be bought, but the free services are very good as well.

Community Foundations will require a blog post of their own, but if you want to visit their websites, you can when you click on the Grantsmanship Center’s map of the states.

Similar to the Grantsmanship Center, the Foundation Center has paid and free services, and the latter are quite good. You can sign up for free newsletters, including the RFP Bulletin which lists current grant announcements.

Grantstation requires a paid membership for searches, but you can sign up for a newsletter that posts current grant opportunities.

The Nonprofit Times offers a free searchable database of corporate donations.

Fundsnet gives you a searchable index by topic as well as recently announced grant opportunities.

Don Griesmann on Charity Channel provides lists of open grant opportunities. You have to join, but it’s free. Here is a sample grant list.

The internet offers grant resources that have been collected by type of grant sought.

The School Grants website has a list of government and foundation funders of educational projects along with other grantwriting resources.

Another place where grants for education are posted is Grants Alert. You can sign up to receive updates by email.

The organization Connect for Kids lists grants for organizations serving children.

The Community of Science website says it will “search the world’s most comprehensive funding resource, with more than 25,000 records representing nearly 400,000 opportunities, worth over $33 billion.”

The University of North Carolina provides grant leads for researchers.

In many cases, you may have to further filter or elaborate upon the information you receive through these collections of grant sources. Grantseeking is labor-intensive, but the payoff can be great. Good luck.
