The Pennsylvania Register
Every law Pennsylvania has passed
55,382 acts of the General Assembly, from William Penn’s first assembly in 1682 to 2026. Until 1874 much of the Assembly’s work was “special” legislation for a single person, company or town: a divorce, a road, a tavern license. That year’s constitution barred local and special laws on most subjects, and the yearly count fell; lately it is about 150.
Not yet complete · The state has not yet digitized its session laws act by act for most years between 1851 and 1949. We filled what we could from scans of the printed volumes: every year from 1851 to 1875 and most sessions from 1877 to 1907. A computer read those titles, so they can contain misspellings, and a few acts in each year were missed. Most years from 1909 to 1949 are still thin (marked below). Every other year is complete, from 1682 through 1850 and from 1950 to today.

By decade
Constitution of 18741874–1967
Constitution of 17761776–1789
- 1780s 567
1682–1801: the Statutes at Large of Pennsylvania. 1802–1974: the Pamphlet Laws (Laws of the General Assembly). Both from the scans published by the Pennsylvania Legislative Reference Bureau, which link to each original page. 1975 onward: the General Assembly’s own record of legislation enacted, which adds approval dates and bill numbers. Years the Bureau hasn’t indexed act by act come from the annual Laws of the General Assembly as scanned by the Internet Archive and Google Books: we split each volume into acts by their approval lines, and each one links to its scanned page. Before 1975 each year’s appropriation acts were scanned as one bundle, so they aren’t listed one by one. Proposed constitutional amendments, vetoed bills and reorganization plans are left out. Subject lines are the Bureau’s and the General Assembly’s, not the laws’ full titles.
