How to enquire about the collections at Bletchley Park

We are happy to answer enquiries about the collections held at Bletchley Park. Our holdings are of a specialist nature so you may find it helpful first to refer to the following sources, before approaching the Trust, as we are unable to answer questions about collections held elsewhere.

Official documentation
For additional surviving official documentation associated with the Government Code and Cipher School (GC&CS), such as administrative, policy or operational records (not held at Bletchley Park), we recommend searching the online Discovery Catalogue at The National Archives in Kew, London, particularly the ‘HW’ series of files:

Veteran testimonies
Additional oral histories from Bletchley Park veterans can be listened to at the Imperial War Museum Collection.

A significant quantity of written veteran testimony is also available on-line via the BBC ‘People’s War’ project 

Personnel information
Where individuals are known to have been part of Bletchley Park, this is recorded on our Roll of Honour. In most cases, an individual’s Roll of Honour record includes all the information about them known to us. No complete staff directories or lists have survived, but some incomplete records are held at The National Archives.

While we hold some material concerning the work of the more famous Codebreakers, such as Turing, Welchman and Denniston, personal papers of these individuals are typically held by other institutions with which the individuals concerned were associated. For example, Turing’s papers are held by King’s College Cambridge, and those of other leading figures at Churchill College Cambridge.

History of GC & CS
We have compiled a reading list of recommended books and journals for those interested in the history of CG & CS, as many comprehensive accounts exist. This can be downloaded below.
