I love secondhand books far more than new ones! I especially like books that someone else has gone through first. It’s a kind of connection — and an experience of wondering exactly who has been there before…I don’t mind god-eared （折角的）corners；I don’t mind the coffee stain—who cares? Indeed, I don’t even mind the comments at the edge.  
If it were an orginal classic, then the book would be of some importance. But the fact that its pages have been read and probably loved by dozens of people since it was produced is incredible, fascinating and wonderful. Just think — you can find old books that were touched by people in the nineteen fifties. That is interesting, as those people would probably have just come through World War Ⅱ.
But books from the 20s and 30s are even more wonderful to touch. Was it an old lady who poured over my aging Dodi Smith paperback that I found in a secondhand bookshop?
I once sat in the British Library reading books published in the 17th century, touching them, and the excitement was considerable. Imagine — these are books that people read, touched , and wrote comments about hundreds of years ago. Who have touched these books? What were they wearing? What was their work? How did the books make them think?
Now you see— I am just a woman who likes to explore the past. I like anything except the new. Who wants new things? The smell of the chemicals, the sense of being mass-produced…
No! No!
