Books are so personal aren't they.
Whe we thought we might move several years ago, we chucked a load of old faves in the bin, including some we'd had since we were married.
Now we're still here for good, we keep going to the charity shop and buying new ones, and the shelves are even fuller with titles which we really do want to read, but get overtaken by the local library, because we like - er - just going there!
Charity shops always take books, Goosey, and the bigger ones can sell them on Ebay, so that may be an answer!
