I have some nintendo adventure books that have some writing (pencil) in them.  I know it isn't a textbook, but would it be considered a workbook?  It has a few puzzles and such that need to be solved, once the puzzle is solved, it tell you what page to go to.   I posted one before I realized it had pencil marks in it, as I didn't see them when I first glanced thru it.  It has been requested, so do I mark I can send, then pm requestor and ask if they want it, or do I mark, I cannot send...  and if I do that, is there a place to put the reason why and ask if they still want it...

I'm not sure those are allowed.  Wouldn't it be similar to a child's activity book?  I'm sure someone will clarify...

To me they would fall under the same category as a coloring book. Once the puzzles are done, the book has no use. I wouldn't consider them postable. That's my personal opinion though and don't know if there is an official site stance on activity books.  I will see if I can find anything concrete.

You can try PMing, but you definitely cannot send the book without an answer. The site allows ANY book (the is allowed on PBS) to be sent under properly followed textbook/workbook rules.

It is not an activity book like a coloring book.  It is a regular paperback novel, except that it has a few puzzles that the reader needs to solve to get to the next part of the story.

Since you've already posted the one, PM the person and see if they mind (but make sure you cancel if they do).

I'd take the others off your shelf since they are written in and post them in the Book Bazaar, someone else may not mind and that's a legit way to do it.
