<p>I plan on selling my books next quarter.
Is it okay if I write in it or highlight in the books? Would it lower the value?</p>
<p>Thank you!</p>
<p>It depends on who you are planning to sell to. Yes highlighting and writing in the books does lower the resale value if you plan to sell it back to the stores, but if you are going to sell it to another student it depends since some people like having important parts marked for them.</p>
