These books have three layers of history to them. Firstly, they've travelled around the world with us. My mum found them in a second hand bookshop on Islay. From there they've travelled with us from Scotland to Holland, to the US, back to Holland, and now to Norway!
Secondly, they're a window into the life of a school boy 100 years ago, with personal touches like "GRAMMER" written on the bottom of Lower English so he can see what book to get out of his bag, and his homework written on the back inside cover.
We know who he was because he wrote his name and address in the front inside cover of both books.
Thirdly, of course, they are a history of English, with the origins and meanings of words, and how grammar has developed.
