Hein Online


About Hein Online

Hein Online is an international database that provides searchable full text access to numerous legal sources. The database contains full text e-books, US and core international journals, Treaties , statutes and cases all in PDF format, which is useful for working out the original pagination. Hein Online, produced by the William S. Hein Company, includes the vast majority of the entire United States law review literature from the nineteenth and twentieth centuries. Its search tool retrieved virtually all of the over 1.4 million articles in that database.

Hein Online provides full access to complete runs of more than 500 Law Journals . It also includes the Federal Register, Treaties and related publications, U.S. Supreme Court materials, and U.S Attorney General Opinions. Other libraries include the Foreign and International Law Database, European Center for Minority Issues, English Reports, Legal Classics Library, and the Philip C. Jessup International Law Moot Court Competition Compendium.

Hein Online, though wonderfully comprehensive in its coverage of law reviews published by law schools, omits some of the legal journals published by university presses, learned societies, and commercial entities.
