Completely off topic, but I'd like some advice......

Don't know how many of you are members of paperbackswap, but I just got a book today that I had ordered and not received......almost 3 years ago.  Postmark is from 6/1/13!  I looked it up on my transaction page, and I have the option to mark it received.  So my dilemma is, should I mark it received or not?  Part of me thinks yes (I did receive the book), but part of me says no (it's a book I wanted and thus re-ordered and got). Thoughts?
