HeinOnline: What It Is, What's Inside, and How to Get Access

What Is HeinOnline Used For?

HeinOnline is the go-to database for historical legal research. Its signature product is the Law Journal Library, a collection of thousands of law reviews and legal periodicals scanned page-for-page back to their very first issues — coverage that reaches deeper into the past than the general research platforms. Beyond journals, it holds historical federal and state statutes, the U.S. Statutes at Large, treaties, presidential and government documents, and specialized collections on legal history, making it invaluable when you need an old article, an original enactment, or a primary source as it appeared at the time.

Is HeinOnline a Legal Database?

Yes, but it occupies a distinct niche. Where Westlaw and Lexis are built for current case-law search, statutory annotation, and citators, HeinOnline is built for archival depth and fidelity. Its documents are image-based PDFs that reproduce the original page exactly, which is ideal for citation and historical accuracy. It is a legal database, just one optimized for retrieving the historical and scholarly record rather than for checking whether a case is still good law.

How to Get Access to HeinOnline

HeinOnline is a paid subscription, but most people never pay out of pocket. Access almost always comes through an institution: law schools and universities, law firms, courts, and a great many public and state law libraries subscribe. If you are a student or faculty member, log in through your library’s databases page. If you are a member of the public, check whether your public library or the state law library offers HeinOnline to cardholders — many do, sometimes remotely. Our free legal research tools guide covers other no-cost routes to scholarship as well.

Who Owns HeinOnline?

HeinOnline is produced by William S. Hein & Co., Inc., a legal publisher founded in Buffalo, New York, with a long history in the legal-periodicals business. HeinOnline grew out of the company’s print reprint and microform operations as the digital home for its enormous back catalog, which is why its archive runs so deep.

Inside the Law Journal Library

The Law Journal Library is what most researchers come for. It contains the full runs of thousands of law reviews and legal journals — including titles long since digitized only here — with every volume searchable and downloadable as a faithful PDF. Because it captures complete back files, it is the reliable way to find an older law-review article or trace how scholarship on a topic developed over decades. It pairs naturally with our legal journals directory, which points to journals’ own current sites for recent issues.

HeinOnline vs Westlaw and Lexis

These tools complement rather than replace each other. Reach for HeinOnline when you need historical materials, a full journal back file, or a primary source in its original form. Reach for Westlaw or Lexis when you need current case law, statutory annotations, editorial summaries, and a citator to confirm a precedent’s status. Many serious researchers keep access to both, using each for what it does best. For a fuller map of the options, see our legal research platforms overview.
