For those who need old books: They are sun-faded, but the contents are relatively clean and should be readable without issue. There are yellow highlighter marks in places. I didn't find any writing, but I haven't checked every single page, so there might be some writing with a pen or other writing instrument. I would appreciate your understanding. Please feel free to comment if you have any concerns. Please refrain from purchasing if you are overly concerned about minor details, as this is a casual inspection. To ensure a smooth transaction for both parties, please be sure to ask any questions you may have in the comments, and consider that these are used items before making a purchase. Thank you.
