This particular section of the guide is intended to make it easier for those looking for information about specific government contracts. While some of the sources go back over 50 years, it does include information on more recent contracts that have been awarded as well. We are constantly on the look out for sources for awarded contracts, but currently there are time periods where sources are limited.
There are a few things to note:
For anyone doing research on Civil War era contracts, newspapers specifically those in Washington, D.C. like those found in Chronicling America, may be helpful. Many notices about contracts to be let were posted in papers like the Evening Star, National Republican, and Daily National Republican under the heading of PROPOSALS or ARMY SUPPLIES. You would need to search for what is being contracted and if you are using Chronicling America, limit to dates and publications to narrow down your search results. Finding who was awarded the contract may be more difficult. There are several agencies who were involved in government contracting in some fashion this is from the National Archives finding aid for the records of the Federal Supply Service:
Predecessor Agencies
In the Department of the Treasury
In the General Services Administration
If you are looking for statistics, the Federal Procurement Data System (FPDS) includes reports, and sources like the Statistical Abstract published by the U.S. Census Bureau until 2012 have very high level data. The sources included here can also be used to get basic numbers and totals. The Government Accountability Office (previously the Government Accounting Office) will often do infographics on their blog (example from 2019) as well as reports like CONTRACTING DATA ANALYSIS Assessment of Government-wide Trends.
Prior to the creation of electronic source the government did occasionally make the effort to capture information in print sources.
There are some sources for information related to both World War I and World War II. However, the information is very limited, and in the case of World War I less straightforward to use and find. To date, these are the best sources we have found, but there are other documents that may have looked at particular products and situations
In 1941, an article listed sources for contract awards information that included – though many of these may no longer be available. It also mentioned that the Federal Reserve Banks and branch banks Defense Contract Service has lists of contracts already let and that they could be found in the daily papers like the Wall Street Journal and New York Times.
The following titles link to fuller bibliographic information in the Library of Congress Online Catalog. Links to digital versions are provided when available.
These are the limited sources in print prior to the advent of sources like the Federal Procurement Data System and USASpending.
Much of the information for more current contracts is digital. Currently the Federal Procurement Data System or FPDS (previously the Federal Procurement Data Center) part of the General Services Administration is the biggest aggregator of information on awarded contracts. However, some limited data is available for military contracts has been digitized by the National Archives. If you want to understand the history of government contracts data the GAO published two reports The Federal Procurement Data System -- Making It Work Better, 1980 (PDF, 2.8 MB) and Reliability of Federal Procurement Data, 2003 (PDF, 45.6 KB). CRS published two reports at the end of 2020 Tracking Federal Awards: USAspending.gov and Other Data Sources (PDF, 743 KB) and Tracking Federal Awards in States and Congressional Districts Using USAspending.gov.
The GAO as well as more overview reports often at the request of Congress. For example, there is an annual assessment of weapon systems (example from 2019), the annual overview of NASA projects (example from 2019), etc.. The Congressional Research Service has also produced reports like Defense Acquisitions: How and Where DOD Spends Its Contracting Dollars and Federal Research and Development (R&D) Funding: FY2019.
