The Laws of Pennsylvania contain laws enacted as amendments to the Pennsylvania Consolidated Statutes, the official statutory codification established by the General Assembly under the act of November 25, 1970 (P.L.707, No.230). These laws have been incorporated into a separate official publication since 1975.
The Laws of Pennsylvania, also referred to as the Pamphlet Laws, have been recognized as official law since December 1, 1801. Acts are numbered by the Department of State and published by the Legislative Reference Bureau as separate official documents known as slip laws before publication in bound editions as the Laws of Pennsylvania.
This webguide, created by Widener University's law librarians, provides a comprehensive list of Pennsylvania related legal resources available on the web and describes how to determine a legislative history. A legislative history is the chronology of legislative action. To trace this legislative action, a researcher must uncover the sources of legislative information that lead to a bill's passage.
