There are different types of bookstores. One which deals with fictions and non-fiction which you see at the airports and malls. The second is the stationary ones which sell school and college books. Which one do you want to start?

I ran a bookshop some fifteen years ago and it flopped very badly because I could not decide which books should be kept. If you want to start an independent bookstore then here are my suggestions-

1. Do not buy and sell every book, but be selective and have a taste. Have only the best sellers.
2. Avoid vulgar and violent books but prefer self-help and other useful ones.
3. Don’t make a big shop, it will cost you more and you won't be able to save money.
4. Host literary reviews and invite popular writers at your place to interact with the readers.
5. Hire a staff who is excellent at organizing the bookshelf. That should be his interview. Give him a shelf and check how minutes he takes to arrange the books neatly.
6. Buy books directly from the authors at a good discount.

I hope this advice should help you a lot.
