Purdon's (unofficial) online

West's Unofficial Purdon's Pennsylvania Statutes is online and linked from the PA General Assembly homepage. The website allows free access to an unannotated version of West's Purdon's Pennsylvania Statutes and Consolidated Statutes. There is a basic natural language searchbox. Links to annotations and cases appear on the search results page, but you have to pay by credit card to go to those links if you don't have a Westlaw account.
