Bloomsbury will move the Churchill Archive to a redesigned platform during July 2023. This is expected to happen in the week beginning 10 July.
If you already have a personal account on the Churchill Archive, this will not be migrated to the new platform, and you will need to create a new personal account in order to continue using it. Bookmarks saved to personal accounts on the current site will not be maintained, so Bloomsbury recommends bookmarking pages within your browser if you wish to keep a note of them. After you create a personal account on the new platform, it will again be possible to save items there.
