The artificial accumulation of documents in this series mostly concern business conducted before the parliament and council. They are of two main types: copies of parliamentary statutes sent for information to the Exchequer; and petitions, proceedings and agenda of the King's Council and of the council in parliament, including Gascon matter.

Other documents present in significant numbers include lists of summonses issued for parliaments, and some original writs and returns for the election of members of parliament. The series includes also some draft and original bills, and copies of statutes made for official or private use.
