“A woman spent about ten minutes looking around the shop, then told me that she was a retired librarian. I suspect she thought that this was some sort of a bond between us. Not so. On the whole, booksellers dislike librarians. To realise a good price for a book, it has to be in decent condition, and there is nothing librarians like more than taking a perfectly good book and covering it with stamps and stickers before – and with no sense of irony – putting a plastic sleeve over the dust jacket to protect it from the public. The final ignominy for a book that has been in the dubious care of a public library is for the front free endpaper to be ripped out and a ‘DISCARD’ stamp whacked firmly onto the title page, before it is finally made available for members of the public to buy in a sale. The value of a book that has been through the library system is usually less than a quarter of one that has not.”
