OECD Revenue Statistics provides detailed statistical data on tax, social security, and other revenues of OECD member country governments. Data are broken down by type of tax - at a very high level of detail - and level of government.

Budget of the United States Government, Fiscal Year 2003, Appendix contains detailed information on the various appropriations and funds that constitute the budget and is designed primarily for the use of the Appropriations Committee. The Appendix contains more detailed financial information on individual programs and appropriation accounts than any of the other budget documents. It includes for each agency: the proposed text of appropriations language, budget schedules for each account, new legislative proposals, explanations of the work to be performed and the funds needed, and proposed general provisions applicable to the appropriations of entire agencies or group of agencies. Information is also provided on certain activities whose outlays are not part of the budget totals.
