Special thanks to Rebecca Sharp, Archives Specialist and Rose Buchanan, Archivist at the National Archives in Washington, DC, for writing this blog post.

The National Archives in Washington, DC, provides access to U.S. Supreme Court appellate jurisdiction case files beginning in 1792. To make a successful request for a specific Supreme Court record, you must first determine the case file number and provide the number to our staff. This number is crucial for us to be able to search for and locate the appropriate case file(s). An overview of Supreme Court records at the National Archives is available online.

Below is an explanation of three online sources for identifying the case file number.

Search Tips

  • If you do not find a case listed in the year that it was decided, check the year before and after the decision.
  • If the case is "Miscellaneous" make sure to include "Miscellaneous" as part of the case file number.
  • If you are researching a case involving a ship, search various terms including: ship, schooner, brig, the name of the ship, the name of the ship’s owner, etc.
  • Search for both the defendant’s and the plaintiff’s names.

The Index to Appellate Case Files of the U.S. Supreme Court, 1792-1909 is available digitally through the National Archives Catalog (National Archives Identifier 1537559). To begin searching, click on the “search within this series” button. The cards are arranged alphabetically by party's name.

Below is an example of an index card for Plessy v. Ferguson. The file number 15248 is the case file number.

Engrossed Dockets, 1792 – 1995

Three microfilm series of Engrossed Dockets of the U.S. Supreme Court have been digitized and are available through the National Archives Catalog (National Archives Identifier 1524561). Click on the “Search within this series” button. Browse until you find the appropriate year span. If the docket book does not include an index, you will need to search page-by-page and line-by-line until you find the case file number of interest.

From 1792 through 1933, the case file numbers are strictly numerical. For example, the case file number for Schneck v. United States is 26484.

From 1934 through 1970, the case file number consists of the docket number and the October Term (O.T.). For example, the case file for Korematsu v. United States is 22 O.T. 1944.

The filing scheme transitions in 1970. A 1970 case file may be either the docket number and October Term or the last two digits of the year followed by a dash and then the docket number. From 1971 through the present, the case file number is the last two digits of the year followed by a dash then the docket number. For example, the case file number for Roe v. Wade is 70-18 (filed in 1970).

Reports, 1957 – Present

A citation from the U.S. Reports is insufficient for staff to locate a case file as it only includes the volume number followed by the page number.

Beginning ca. 1957, U.S. Reports include the case file number. The case file number will be listed near the top of the first page related to the case. The October Term should be listed at the top of the page (or the top of the opposite page) as well.

For example, the U.S. Reports citation for the case Epperson v. Arkansas is 393 U.S. 97. From 1934 through 1970, the case file number consists of the docket number, the October Term (O.T.), and filing year. The court issued case file number for Epperson v. Arkansas is 7 O.T. 1968--this is the number that National Archives staff need to locate the record.

The citation in the U.S. Reports for Roe v. Wade is 410 U.S. 113. Starting partway through 1970 to present, case file numbers consist of the last two digits of the year followed by a dash then the docket number. The case file number for Roe v. Wade is 70-18--this is the number that National Archives staff need to locate the records.

U.S. Reports for the years 1792 through 2003 are available online through the Library of Congress. The remaining portions of the 2014 term are available through in a preliminary print version. U.S. Reports for the years 1991 through 2014 part are available through the Supreme Court of the United States. The remaining portions of the 2014 term are also available online in a preliminary print version.
