There’s a very cool diary of a World War I veteran created from his journal and pictures by his grandson. If anybody would like to do something like this with any of my family members, I’d be happy to help out on the technical side!
On a similar note, my grandmother had a blog. She wrote out all the stories long hand and mailed them to my mom who typed them in and posted them. Then my aunt would print them out and take them over to my grandmother’s for her to see. She was very proud of being an author – she loved sharing stories.
