Most unpublished manuscript material in the Conservative Party Archive is subject to a general 30-year access restriction, while a few series are embargoed regardless of date without permission from the Conservative Party (see Access Restrictions).
From 2012, files newly de-classified under the 30-year rule (see Access Restrictions) and any other files which the Conservative Party has agreed should no longer be restricted, will be listed here, shortly after 1st January each year, as an aid to researchers.
