White House earmarks database

The White House Office of Management and Budget has put a database of Congressional earmarks online. You can download the data or browse by agency or state, with more features to come. A disclaimer, though, makes me doubt its worth:

This database is not designed, and cannot accurately be used, to identify the individual congressional sponsors of earmarks. In addition, the recipient listed in the database may not in all cases represent the ultimate beneficiary of the earmark. For example, if the Federal Government provides funds to a specific recipient (e.g., a City), that recipient may then provide the funds or benefits to another entity and may not be required to identify the ultimate beneficiary to the Federal Government.
