There are a few things to keep in mind when selling college books online. First, check the ISBN number to make sure it is the most recent edition. If not, it may be difficult to find a buyer. Next, take good pictures of the book- front cover, back cover, and any pertinent pages inside (e.g., tables of contents, index). Make sure the photos are well-lit and clear. Finally, include all relevant information in the listing description- title, author, edition number, condition of the book (e.g., new, lightly used), format (e.g., hardcover, paperback), etc. By following these tips, you should have no problem finding a buyer for your college books!
