Buying books isn't easy.
You have to browse through them, compare them to other books, look at prices, and more.
And remember, don't judge a book by it's cover - literally. If you're buying books for other people, you might feel like you really need to buy the right books. If this is the case, calm down. Buy books you think sound good. Think of the person's reading abilities and what types of books they like. For more, read on:

Buying book for yourself
First thing's first. Before we get into buying books as presents, you need to know how to buy books for yourself. These are some questions I've been asked when people are wondering about buying books:
How much money should I bring?
When you're going to the book shop, how much money should you bring? If I were you, I'd bring €20 per book, to be on the safe side. If you do that, you won't be going home without change. Many books cost about €20 ($26, £15), most of them a little less.
Where are the best bookshops?
I don't know all of your local bookshops, but here are some good bookshops that you probably have near you: Borders, Barnes & Nobles and Eason's.
Hardback or paperback?
Paperback is always cheaper, so I get paperback. Do you like to read your books, or leave them on the shelves to look impressive? If the answer is leave them on the shelves, buy hardback, but if you just enjoy reading a good book, I would advise you to buy paperback.
But those aren't the only important things. You need to know that you're not being sold books for more than they're worth. Fist of all, a paperback book shouldn't usually cost any more than twenty euros, which is $26, £15.
Hardback should be less than thirty (go to xe.com to get other currencies for that).
A second-hand book should be ten euros (about eight pounds, or 13 dollars), unless it's old or very valuable.
