When you work in a bookshop, you can usually tell when a fellow bookseller comes in. They’ll be the ones subtly straightening all your book displays and re-imposing alphabetical order on the poetry section.
If they work for a bookshop chain, you may hear them utter the words “staff discount” at some point to their friend, before walking out empty-handed.
One of the perks of running a bookshop is that you often receive ‘proof’ copies of books, those being, for the uninitiated, uncorrected draft versions of forthcoming publications. If you’ve ever read a book and thought:
What this really needs is a few spelling mistakes, some confusing typos, a front cover entirely comprised of writing and absolutely no re-sell value
then proof copies are definitely for you.
