Bristol Record Office

From the Wikipedia page

Bristol Record Office was established in 1924. It was the first borough record office in the United Kingdom, since at that time there was only one other local authority record office (Bedfordshire) in existence. It looks after the official archives of the City of Bristol, besides collecting and preserving many other records relating to the city and surrounding area for current and future generations to consult. It moved from the Council House to newly converted premises in the former B Bond Warehouse in 1992. The office is formally recognised by the Lord Chancellor for holding public records and it acts as a diocesan record office for Bristol diocese.

Major deposited collections include those of J S Fry & Sons, chocolate manufacturers, 1693-1966, and Imperial Tobacco (formerly W D & H O Wills, tobacco manufacturers) late 18C-20C. However for many years one of its best known holdings was a single volume of judicial case papers bound up from the actual skin of the 19th century executed murderer, John Horwood.
