I was looking at my wish list and keep wondering, why some books state last posted on such and such date. 


Maybe I am being dense, but it seems to me that if that book was last posted in 2008, someone had requested it and the person who has it is keeping it.  Wouldn't that cause the book to be removed from the system?  And my requesting it is a lost cause?



ISBN-13: 9780872168299 - ISBN-10: 0872168298 - Book Type: Paperback
Wish Date: 5/2/2010 - Your position: 1 of 1 - Last Posted: 10/20/2008 - Estimate: N/A

edited to see if I can keep the sentences from overlapping

So you can see if it has ever been posted on the site.
Some are more accurate then others.

It does not mean one specific copy of a given book but rather the last time that anyone, in the whole system, posted a copy of that edition of that book. If a book has few copies because it is old, or extremely popular or long out of print then maybe no one has posted it all year. So if it says that you are 4th in line, and it was last posted in 2007, it might be years before you would get it, if ever.

But it means ALL copies, not one specific copy.

Some books state last posted because there is a record of it being posted, but there isn't enough data or its been too infrequent to calculate an estimate on when you might get it. It doesn't mean that there is a copy available in the system since that date, just that someone posted one on that date.

someone had requested it and the person who has it is keeping it. Wouldn't that cause the book to be removed from the system?  And my requesting it is a lost cause?

I am not really sure where you are going with this. The book listing is never removed from the system and what someone did with a specific copy really doesn't have a bearing on whether you will get a copy unless there was only one ever printed. Yes, it probably means you won't get that copy they received, but doesn't really affect someone else posting the book. You aren't really requesting that copy that was posted in 2008, you are wishing for the next copy that is posted into the system.

Books in the system are entered by ISBN, usually as they're published, not because they've ever been posted here. The site gets the ISBN and original book info from other sources. So when you do a search you're not always seeing books that have traded here, just books that have existed under that ISBN and could be posted at any time. And sometimes publishers re-use ISBN numbers. So you might go pull up a book to post by ISBN and it be a different title.

Since the site is getting new members all the time, there's really no telling how often a 30 year-old book will be posted. The older they are the more likely there will be fewer of them around to trade, especially if they don't age well, but someone may run across a copy in a garage sale or used book store. 

How long you wait for any WL book is up to you, but maybe you'll get lucky. Hard to tell when new members are joining all the time.

The records don't go back beyond 2006-2007 in my experience.  They may have beenposted in 2005-2006 but there's no record.  In fact the earliest "last posted" book on my WL is 2007.  I really hate looking at that one.  And no one has to repost books that they've gotten here.  Many people get books and then leave taking their books with them. 

One thing I've been trying to figure out is whether the books that are RWAP'd are included in the "last posted" category.  It seems like it would, but the one I got that had the thumbprint stain and RWAP'd isn't showing up as having been posted.  So I don't know because it seems like I remembered that ones I'd gotten before did show up as "Last posted on".

Ruth, IMO it's likely that RWAP show up as posted in the system.  I know canceled transactions appear.  Over a year ago, a book was posted to me.  Very shortly, the sender pm'd that her DH wasn't ready to part with it yet and canceled the order.  I'm still at number one, the book hasn't been posted into the system again, and the transaction that didn't happen still appears as the last date.

It is my experience that those dates shown on the WL are not accurate. Often I will see that several copies were posted one week on a book i am waiting for, and then 7 days after the last of those books were posted, it returns to "N/A", as if there had not even been a posting of a book. On some books, the data seems accurate and then on others it does not, without any rhyme or reason. I never make assumptions based on that date shown because sometimes it seems to revert to a previous date or as I've said, go back to N/A.

I asked the PBS team about this a while back. (Tried to find their message to quote it, but it has aged off the club communication tab in my account.)

Anyway, the gist of the answer is that a book shows a "last posted" date only if it is still in the PBS system, as in still active on somebody's TBR list or bookshelf. The "last posted" data is thrown away once that specific copy is dropped from the owner's shelf or TBR list.

I asked this because I received a book and then when I went to order a second copy for a friend it showed the book as never having been posted. Made me wonder why, so I asked. (I had deleted this particular book from my shelf and TBR as it was a keeper, so the last posted data got deleted as well.)

Kind of an odd system IMO. Why not keep that data and make the last posted info more reliable? A dozen copies might have been traded last week, but if none were left on hold on a member's bookshelf then you or I would never know and think that it had never been posted.

So, if you see a book with a last posted date that is a couple years old, then what you have is a transacted book that is still sitting on some member's "keeper" bookshelf on hold and is probably not going to be traded. Maybe even an inactive member, there's no way to be sure.

How is that useful data other than to discourage me from WL that ISBN ?

Interesting information, Technomage.  I used to think that no info meant the book hadn't been through the system or that they didn't have a record of it.  Seems like the last time the ISBN had been posted would be info easily kept.  Of course it isn't good if it was lost or RWAP.  In that case neither would be kept since they wouldn't be around or be postable.  Strange system.

Thanks for sharing that information! I have always wondered why some show dates and others don't even when I KNOW it has been posted recently! Another mystery solved!
