Think twice before discarding your used books, they might be in demand somewhere which will help you earn some money. Used books and second hand books are synonymous terms. These days, due to the continuous rise in the prices of books, the demand of used books is gaining heights. Be they your old textbooks or storybooks in which you have lost interest, it does not matter as they have a value of their own. So instead of throwing them out or making a shelf out of them, you can try selling them in any nearby secondhand book shop or on the Net.
It must be kept in mind that all used books are not of the same value or importance. It would definitely make a huge difference if the book belonged to your grandfather and is out of print these days. The book might gain an antique status or if it is in demand, you may gain big money.
Incase of textbooks, the scenario is different, as the price of used text books are mostly fixed at 50% of the original price or more in case there are no updated editions available. The other important factor which determines the price of the old books is their condition like for instance if the book has missing pages, the book becomes worthless.
The used books of famous personalities sometimes gain antique value and are sold in live auctions or on the Internet. In many parts of the world, exhibitions and fairs showcasing and selling used books are held. In a number of websites, used books are sold or auctioned which include all kinds of books from classics to textbooks, from contemporary autobiographies to encyclopedias.
