I've been given some old books that once were in an antique shop that my gran worked in. The logic for them coming to me to get valued is that I did an English degree, but that provides no practical help in this instance! I can see things online about ISBN numbers, but the newest book was published in 1926 so that's not particularly helpful. Does anyone know where I'd even start? I imagined taking them into a shop, but the antiquarian bookshops I've found seem to talk about valuing libraries rather than 4 odd books.
