General Research
Start with the Georgetown Law Library web page. Here you can search the library's catalog, the many electronic databases available, do a Google search, and access other electronic resources available through the main campus library. You can use FirstSearch to locate books on juries and on more specific materials within the subject (i.e., criminal juries, trials at nisi prius, hung juries, etc.), a specific time period, a specific place, or comparatively (i.e., jury trials in the United States and England, or France, Germany, etc.).
With some topics, a wealth of secondary information is available in law journals and historical or social sciences scholarly journals. A select few are listed here to demonstrate the importance of searching the periodical literature, using Lexis-Nexis, Westlaw, HeinOnline and Index to Legal Periodicals, but also J-Stor, Academic Search Premier and Project Muse to name a few indices.
A selection of a few other good secondary sources for legal history is listed below. To find others, use FirstSearch and subject headings English legal history, etc.
These are a few general sources on the early history of American law. Search the library's catalog or other databases under the subject heading American legal history, etc.
