I received this book today. I realize it is an older book (1971 reprint) but there is some sort of liquid damage to about 50 of the pages and the edge of the stain is very obvious when you open the book. This is the first time I have received a book with water damage so I'm not sure if I should mark it RWAP or not.

I read the guidelines before posting my question & it specifically states no water damage to the pages but would this be considered damage? I don't want to mark it RWAP unless I'm absolutely sure it is a problem.

Thanks for any advice :)

Liquid damage in any amount is not postable. Go ahead and RWAP. 

And book age should have nothing to do with it. I have sent out 40-year-old books in great condition. Splash my drink on one? Oops, no longer postable.

Yes, please do RWAP.  PBS rules state absolutely no liquid damage of any kind.

You can ask for your credit back, or not, that's up to you.

Just be polite when you let them know and hopefully the sender will be nice and realize their mistake (they have to acknowledge a RWAP but do not necessarily have to refund your credit) so you can mark it resolved.

But you will not be able to repost the book into the system.

You can offer it in the book bazaar forum though.

Thank you for the advice, I appreciate it! I am going to mark it RWAP. After flipping through it some more, I realized the stain was worse than I initially thought and covers more than half the pages.

I most definitely will NOT repost it! 

Good choice to RWAP, liquid damage is not postable per PBS swappability guidelines:

Overall Condition:

• No damage at all from water or other liquid
• Not soiled
• No stains (exception for cookbooks--see below)
• No mold
• no highlighting, underlining or writing on text pages (exception for Textbooks/Workbooks and travel guidebooks --see below)
