"The Liddle Collection was founded over thirty years ago to collect and preserve first-hand individual experiences of the First World War. The archive includes original letters and diaries, official and personal papers, photographs, newspapers and artwork, as well as written and tape-recorded recollections. Material is arranged within 30 sections, according to nature of service or geographical area, and these are listed in the Summary Guide. This guide also contains subject indexes to uncatalogued material where appropriate."
