What does the condition of the book mean?
Our item information will include the condition and sometimes additional notes in the description too.
Collectable books can be in any condition: They may be signed, a limited first edition, out of print, or have other special qualities that increase the book's value.
A note about the dust jacket: If there is no mention of the dust jacket and the book is in good condition or higher and it is expected to have one; you can assume it is present. Some academic textbooks are published without dust jackets. Board books, annuals and any book older than 1890 is not expected to have a dust jacket.
If you are unsure or unclear about a book's condition, the description or you just want a bit more information about the book feel free to ask.
Which payment method can I use to place an order?
You can pay with most major credit and debit cards and PayPal. We cannot accept orders paid for by cheque, postal order or pro forma invoices.
Why is the book ex-library?
We work with our library vendors to find a new home for their unwanted stock. Purchasing ex-library books through Bookbarn International will actually help benefit them as they will be paid commission on sales. We sell books on behalf of several libraries and all ex-library books we sell were properly de-accessioned before we list them online. Ex-library books are definitely not stolen!
Why does the book I received not match the book cover image?
The book cover image may not represent the actual copy or condition available. The images on our website are intended as a guide and many of them are stock images, particularly books with an ISBN.
Publishers do also sometimes change the cover design and keep the same ISBN causing cover image discrepancies.
If there is a particular cover you are looking for, please contact us and we can provide an image of the exact copy in stock.
Why has the price changed?
Our prices may change down or up from time to time as we aim to provide the best possible price. We cannot offer refunds on an order once it has been placed if the price of the the book changes. The sale price is agreed upon at the point of sale.
