What records can I find in The Mitchell: Registrars and Special Collections?
An official census has been taken every 10 years in the United Kingdom since 1801 (not 1941) but only those returns after 1841 (with a few earlier exceptions) carry details of named residents. There is a hundred year closure so the 1911 census is the latest which can be accessed.
The census records for all of Scotland for 1841 to 1911 have been digitally imaged. Copies of these images, together with a full index, are one of the many resources available as part of the ScotlandsPeople network which you access in the Registrars on payment of a daily fee.
Special Collections holds microfilm copies of the census for large parts of Scotland for 1841 to 1901 (not 1911) which you can access free of charge.
