Books used by students, scholars or professors do not always end up at the state library and instead end up at the local resellers. These stores work as a bridge between those who want to dispose off their old books and those who are looking to buy. Books often tend to be out of publication or are very difficult to buy owing to their scarcity. The best solution to the situation is to buy used books.
It is surprising to see the used books collection that many of these resellers have. From used text books to old magazines and journals, you are sure to get almost anything that you have been searching for. Used college books are one of the most common items that people look for. From astronomy to animal husbandry, history of Everest climbs to that of the ocean's deepest trenches - a huge collection of used books are available at the resellers. It is highly unlikely that you will be able to get the desired college book at the first instance itself. To buy that coveted book you may have to visit a few resellers and rummage through the used books stock before you are finally able to find it.
The biggest advantage of used books is their low prices. But when you buy used books the condition of the book is the foremost thing to consider. It is advisable to check the books, especially to see that the books contain all the pages including the index. Often resellers tend to put an attractive cover to hide the book's damages. You should also be aware of the prevalent market price of the book to ensure that the reseller is not making considerable profits by charging higher than the normal.
Not only can you buy used books but you will also be able to sell used books or exchange used books at the reseller's. Barter of used books is a good idea, as you can always pick up something useful in exchange of books not needed anymore.
So the next time you want to add a missing edition to your National Geographic collection or buy a part of the Britannica Encyclopedia series, you know where to look.
