Case Law & Law Reports

Online guidance to assist with case law research

Although early law reports are of most interest to legal historians, many cases from the 19th century and before are still cited today 

Year books

The oldest available law reports cover the period c.1272 (the early years of Edward I's reign) to 1535. They are written in legal French or Latin and were produced anonymously. There are two modern editions of the Yearbooks: the Rolls Series (Edward I and III) (Old Library) and the Publications of the Selden Society (1307-1321) (Law Library, ground floor). Both series include the original text with English translations. An index created by David Seipp, a law professor at Boston University, is available for all printed Year Books from 1268-1535. The database provides extensive details and a sophisticated search form.

Private reports

When compilation of the Year Books ceased, private reports began to appear, usually named after the reporter. The standards of these reports vary widely, partly because of the ability of the reporter, partly because of unreliable translations from French and Latin manuscripts. 

English reports

Many of the cases reported between 1535 and 1865 are reprinted in the English reports (E.R. or Eng.Rep) which are arranged according to the courts in which they were heard.

These are sometimes called "nominate" reports, as they are normally referred to by the abbreviated name of the reporter
e.g. Co.Rep.(Coke's King's Bench Reports)  These appear in vol. 76-77 of the English reports.

The Revised Reports (R.R.) cover the period 1785-1866 in 152 volumes and duplicate much of the material in the English Reports. All England Law Reports Reprint contains selected cases from the period 1558-1935. 

Searching online for historical law reports

The English Reports (1220-1873) and the publications of the Selden Society are available online via the HeinOnline database. The full text of the English Reports is also freely available on the website of CommonLII (the Commonwealth Legal Information Institute). Reports are browsable by year or by alphabetical sequence. 

To find the English Reports on Westlaw use the Cases tab and enter the party names or citation in the search box. The results can either be read on screen or downloaded as a facsimile of the printed page (click on PDF of Case Report at the top of the results screen.) The same function is provided by Lexis.

Over 800 older cases have also been added to the BAILII (British and Irish Legal Information Institute) site as part of the Open Law project. Search by date or by case name.

The Proceedings of the Old Bailey, 1674-1913 is a valuable record of London’s Central Criminal Court. The searchable archive contains details of nearly 200,000 criminal trials.
