The diaries of war poet Siegfried Sassoon have published online for the first time.
The archive of 23 journals and two notebooks of poetry has been digitized by Cambridge University, which bought the collection in 2009.
Until now only Sassoon's official biographer - Max Egremont - has had access to the complete 4,100-page archive due to its fragile state.
Librarian Anne Jarvis said the war diaries were of "towering importance".
The journals, which are made freely available online, offer a unique insight into life on the front line during World War One.
