I received a WL book today that #1 was unpostable due to some water damage and staining on several pages (in addition to the cover being otrn from the binding near the top of the book, which the member did PM me about  but not the WD or stains) but also apparently came from booksfree.com.  I had never heard of that site but just looked and saw it's like a Netflix for books.  This book also has a barcode and number on it, and there are no markings or stamps to indicate it was sold due to condition or discarded, like I have seen when libraries remove/discard books.  I am thinking about contacting the booksfree site and asking about the book and number to see if it was "not returned" by the member who sent it to me.  If they respond yes, should I report this member to TPTB? 

Yes, i think that is a good idea.

Yes I think you should . Maybe they didnt return them back to that site because they were not in good shape and they would have had to pay for damages. so they pownd them off on someone here..... But I would let PBS know

I got a reply from booksfree.com and it stated that members often purchase books they've rented, so it's possible that's the situation here.  The email said they'd have to check the barcode on Monday to be sure though. 

Maybe a previous owner (not the PBS member) legitimately purchased the book from booksfree.com and later donated it to a thrift shop, FOL sale or traded it in at a UBS. And, at a later date, the PBS member ended up with it?

My library puts a black marker line through the barcodes.  Not as clear as the withdrawl/discard stamp.  But a good way to handle it.

I used to be a member of booksfree and I purchased several of the books I borrowed from them.  Since I didn't have to send them back first to purchase them, the barcodes and everything remained on them, unaltered.  But they were legitimately mine.

Dawn, if you find out it *is* active, you'll want to let PBS know.  That's what they request if one finds out that a library books still active, I would think the same applies here.  I'm sure it'll turn out to be purchased, though...at least I hope!
