Introduction to this Guide

This guide is aimed at introducing non-law University of Pennsylvania students to the kinds or types of laws produced by the federal judicial, legislative and executive branches of government. It also identifies where laws may be found, and explains how primary and secondary authorities are cited, according to The Bluebook:  A Uniform System of Citation.   A bibliography of fundamental legal resources is available for reference and in-depth commentary.  Finally, links to Penn's LexisNexis Academic subscription database, as well as basic government and commercial websites, are available for basic legal research.
