Unless it's a textbook, it is not allowed to have highlighting in it. If it IS a textbook, the condition (including highlighting) should have been agreed upon in a PM beforehand. So you should mark the book received with a problem because it was posted against guidelines.

To see the guidelines for posting books on PBS, check out these two topics:

• Book Condition Guidelines
• What can be swapped here?

I also just recieved a book with underlining (in pencil) across some of the pages.

Its a play called Suberbia, and sone lines are underlined, also on some of the pages a characters name is crossed out and another characters name is written. I want to erase this but fear damage to the book.

Im not sure if I should mark it "recieved with a problem"...I dont want to be mean, and Its not that it bothers me so much, but I feel the rules are there for a reason.

I'm torn.

"but I feel the rules are there for a reason"

This is very right, and if you don't help people learn to read & follow the rules, who will? You don't have to ask for your credit back, but you should mark it RWP. The reason is what if this person sends a lot of books that don't meet the rules, and no one reports them? When are they going to find out they can't keep this up? If no one reports them, they CAN keep it up, because there are NO repercussions! At least make sure the flag gets thrown on their account so that if they are doing it a lot, PBS can confront them on the issue. If it was an honest mistake, it's not going to hurt to have a mark or two on their account. PBS looks for patterns of abuse, not an occasional mistake, so there is nothing mean about marking it RWP.

Please be kind in your PM, quote the portion of the Help Center that indicates this is agains the rules. State that you are not asking for your credit back, but just want them to be aware of the rules so that they don't make this mistake too many times and jeopardize their account.
