Lists of British casualties were published, although it appears not wholly or consistently.
Original War Office lists of men who died, were wounded or declared missing are held on microfilm at the British Library (formerly from the National Newspaper Library collection). To search them it would be necessary to know an approximate date.
Several national newspapers reproduced the lists, notably the “Times”, “Irish Times” and “The Scotsman”. All of these have been digitised and can be searched online, with the “Irish Times” and “The Scotsman” offering “pay per view” downloads of pages. The “Times” digital archive can be accessed via many libraries.
TheGenealogist website provides digital access to the War Office and “Times” casualty lists for members who subscribe at its “Diamond” level.
Local newspapers regularly carried lists and articles on their men who had appeared in the lists. Some are now digitised and available at the British Newspaper Archive and Findmypast. For most it will be necessary consult original or microfilmed copies in local archives.
The unit war diaries sometimes name casualties or include attached lists.
Being included on an official casualty list of wounded qualified the soldier for a wound stripe.
