British History Online was created by the Institute of Historical Research and the History of Parliament Trust. It is a digital library, mostly free of charge, containing some of the core printed primary and secondary sources for the medieval and early modern history of the British Isles. Freely available content of legal and parliamentary interest includes Raithby’s Statutes of the Realm of the period 1628-1701, the full text of Acts and Ordinances of the Interregnum 1642-1660, edited by C.H. Firth and R.S. Rait (3 vols, 1911), and some early volumes of the House of Lords and House of Commons Journals. Subscription is required for access to some content including Calendars of State Papers.
