Documents lie at the core of this website, each one dated and sorted chronologically (by default) in search results. Most are images in PDF format of original paper documents scanned or filmed for the site. There are also transcripts of speeches and interviews, press articles, photos, videos, and more. The document database contains tens of thousands of items and permits complex searching.

Files are multi-page PDFs from which most of the documents on the site are selected. All of Mrs Thatcher’s official files from No.10 are available in full on this site (paper copies are stored at the National Archives in the series PREM19), as well as most of those of Geoffrey Howe and Nigel Lawson as Chancellor (stored at TNA as series T639 and T640).

Guides are articles about key events and topics. Many were written to accompany annual releases of Mrs Thatcher’s private and party papers at the Churchill Archive Centre in Cambridge.
