This page of the return provides a complete grants list. Note that while grantee addresses and a brief description of the grant is requested by the IRS on the form, in many cases all you'll see is a listing of recipient names and dollar amounts of grants.
If you are researching one of the larger foundations, you won't necessarily have to work with a 990-PF in order to study a grants list or review basic financial data. The larger foundations often have web sites, and/or issue annual reports. Foundation web sites and annual reports often provide a description of the grant in cases where the 990-PF does not.
Tip: Sometimes the statement "see attached" is written on page 11. If this is the case, then look toward the end of the return for the schedule of grants.
Tip: Check to see if the foundation has provided any grant listings in part B, "Approved for future payment". If so, then you potentially have two years' worth of grants in one 990-PF.
