This guide provides a brief introductory and explanatory overview of resources for low- and no-cost (i.e., free) legal research, online, focusing on United States/American law.


The purpose of this guide is to provide a brief introduction to and explanation of resources for low- and no-cost (i.e., free) online legal research, with the focus upon United States/American law.

The guide is organized according to a common dichotomy of legal resources/materials (please see here and here for two explanations) into: 

  1. Primary sources/authorities
    - Judicial (cases, dockets, rules of court)
    - Court & related websites
    - Legislative (constitutions, statutes, ordinances, legislative history)
    - Administrative (agency rules, regulations, decisions) materials
  2. Secondary sources/authorities
    - Explanations of "The Law"
    - Research Guides & Copyright-related

Please note that it is the intent of this guide to refer and link to as many free (i.e., no-cost) online resources/materials as possible.
