A friend went into her local Books Etc. to have a look at a book recommended to her (although she won't be a friend for much longer if she continues to go into her local Books Etc. looking for books recommended to her - Are you reading this!?). Anyway, it was The Power of Now by Eckhart Tolle, published in 1999 since when it has been on the New York Times bestseller list and translated into 33 languages. She asked the assistant for The Power of Now by somebody Eckhart. The assistant had not only not heard of it but failed to find it on their database and confidently announced that it didn't exist and she was mistaken.
I knew about the book instantly so this obviously and conclusively proves the inherent superiority of independent bookshops! Or sort of. Case closed my friends, case closed. Ha!
