William S. Hein & Co. / HeinOnline

What It Does

HeinOnline is a subscription legal-research database launched in 2000 by William S. Hein & Co., a family-run Buffalo-area publisher of legal materials operating since the 1920s. It provides image-based, true-to-print access to historical and current legal content: law journals, case law, statutes, government documents, treatises, legislative history, world constitutions and international treaties.

The database is widely used by academic law libraries, courts, government agencies and law firms, particularly for historical and archival legal research where its full-run scanned journal collections are a primary draw. The company also continues to produce print legal publications.

What We Found

HeinOnline states it holds more than 245 million pages of content, having grown from 25 law journals at launch in 2000. It won the American Association of Law Libraries’ New Product Award in 2001. The platform’s Law Journal Library is one of its most heavily cited collections in academic research.

What We Haven’t Verified

• The “245 million pages” figure is the vendor’s own.
• Pricing — HeinOnline sells institutional subscriptions and does not publish list pricing.
• Current company headcount.
