The Sessional Papers are also known generally as the Parliamentary Papers. Until 1969, the Sessional Papers were grouped and published as Bills (legislative drafts), Reports of Committees/Reports of Commissions, and Accounts and Papers (statistics, census data, etc.). Since 1969 the Sessional Papers have been published under Bills, House Papers, and Command Papers. The Sessional Papers will include census data, statistical information and abstracts, and correspondence from officials. For more explanation of the British Parliamentary Papers, including what Bills, Reports, and House Papers are, see the HCPP summary.
