Legal Research Basics


There are many sources for free legal information on the Internet, especially for legislative bodies and regulatory agencies. It can be cost-effective to begin your research on free (but authoritative) websites before moving to fee-based legal databases.

Always remember:

  • Evaluate internet sources for authenticity and credibility
  • Websites often do not cite to primary law - move to specialized legal databases to find citations and confirm results
