I found a website that is collecting pictures, letters, postcards, souvenirs and other items from 1914-1918 relating to World War One. It's at www.europeana1914-1918.eu/en. I have put Captain Arthur Gibbs' letters home. (He was Granny's Dad.) It's in a pdf file, which is also here, in case you want it. If you search europeana for 'Gibbs' you can also find it.
