Go to the Grants Information section of your local library. The library reference information person should be able to help identify local service organizations such as Rotary ect. Should also be able to assist in the identification of local trusts, family and corporate foundations, and other charitable institutions. In order to maintain their tax status, local trusts and non corporate family foundations must expend a specified percentage of their liquid assest each year. Therefore, the tax returns will list all of the awards or grants given in the previous year.
