I actually don't think finding a book is harder, either. If I know what I want, I just walk up to the counter and ask. If it's in stock, I go grab it. If it's not, they order it, tell me it'll arrive within a month, and I swing back buy to pick it up it about 2 days later. If I don't know what I want, the staff recommendation slips most independent bookstores put out are great, especially now that I've gone enough times to know which staff members share my reading tastes. And have led me to many, many more delightful books and authors I wouldn't have tried otherwise than Amazon's sad attempts at getting something useful out of collaborative filtering. ("You liked Pride and Prejudice? Well, how about... Sense and Sensibility!! Ta-daaaa, isn't AI amazing!?")
What's BAM?
Overall the whole experience is way better. Finding a book is a tiny bit harder (emphasis on tiny), but honestly, I'm not in a hurry when I'm in a bookstore, so I don't care.
