I have inherited the above box set from my dad and on investigation it seems it is quite a treasured and possibly valuable set. It sat on my dad's bookshelf for a number of years and although it is no longer wrapped up, I don't think the books have really been read (from memory we were told we had to read the old paperback versions instead). So, am I right in thinking they are valuable? And if so, should I be looking after them better than just transferring them to my bookshelf?
