Quick update: Foundation Directory Online just passed a milestone we're pretty proud of. There are now over 3 million grants in the Search Grants database!
The full set is available for searching in FDO Platinum and Professional. Plus includes the grants from the top 10,000 foundations (determined by total giving); Premium has the grants from the top 20,000. Our indexed grants are generally of $10,000 or above, although we do have a growing number grants of $1,000 or above from the largest foundations as well. Because several hundred foundations participate in our eGrant Reporters program sending records of their grants to us directly, we're able to publish those foundations' grants even before they're available in their 900-PFs. For example, a quick search in FDO Professional just now returned over 13,000 grants from 2012 (year authorized) and another 157,000 from 2011.
We're always working hard to add more and more grants to the database while at the same time maintaining high standards for the accuracy and quality of our data. We hope this pays off for you in your search for funding.
