QuieroLibros is the best way to find and buy secondhand books. You will be able to see all the available books in your area, by their title or by their cover.
How does it work?
You just have to point your camera to a book you want to buy or sell, and we will help you to determine its condition. You can also check if it has any markings on it, if there are any notes, or if it has been checked and is damaged.
Once you have determined its condition, you can choose to buy it or sell it. If you want to buy it, you just have to enter the amount of money you want to pay, and we will take care of the rest.
