Reprint is the second (or multiple) printing of books after the first printing, with little or no changes. When a book is republished, the layout, book number and layout remain unchanged, but the cover and title page can be redesigned. Under normal circumstances, the barcode of China Standard Book Number will remain unchanged, but if the pricing is adjusted, an additional code must be added after the original barcode (the whole barcode needs to be reapplied).
