Hello, having amassed a miniature library of 18thC & Napoleonic books on Infantry to research a book 15-20 years ago, I no longer read them & with online/digital print none of them seem to get any interest on Amazon now. Theres 9 big boxes of them piled up in the guest room. But dont really want to just skip so many original old books. Includes Infantry manuals in practically every west European language. They are in South London UK. What best to do with them?
