What happens when a member receives a book but doesn't mark it as received?  I sent the book with delivery confirmation, so when I look at the details I can see that it was delivered on January 21st.   I sent a personal message to the member asking if they got it because it shows that it was delivered, but I didn't get a response.   Is it eventually marked as lost if they don't respond, even though it says it was delivered?

DC does NOT mean that the reciever actually got the book. It just means it was delivered to an address, might not be the correct one. I've had one or two books sent out and they showed being delivered but had been put in the mail box for 190 instead of 109. 

If you used PBS DC then you'll already have your credit.

There's a date on your screen that is the system action date. On that date (or really just before that date), the system will take some kind of action. It will either mark the book lost or it will mark the book received. Which one it does depends on whether it thinks the account is active or not. The exact algorithm used to determine "active" is not published.

If the account shows signs of inactivity (such as no log ins, unanswered PMs or requests) they'll mark it received instead of lost. 

Of the 3 books that went lost enroute to me-1 shows a deliver scan but I never got that book. 

Recently I had a package from Amazon go lost.  It showed a delivery scan.  I waited a few days, no package.  I called the post office. It was sitting at my local PO for no known reason.

Yup...it's what everyone else says--and as xengab said, you already got your credit.  One of the benefits of using PBS DC is "credit insurance".   If you use PBS postage, you receive your credit when you mark the book mailed.  If you use PBS-DC, you get your credit when the book is first scanned by the PO.  Your credit won't be taken away from you if the book is never actually received or marked received by the recipient.

The receiving member could also be out of town...whatever the reason they have not marked it received, you have your credit, your job is done.

whatever the reason they have not marked it received, you have your credit, your job is done.

Yes, it is true that you already have your credit. But, I like to send a PM the receiver a few days before the system is going to mark the book lost, to ask them if they actually received it, and to let them know that I did mail it out on time.

The credit that they get back when the book goes lost in the mail comes out of PBS's pocket ... making the site more expensive for everybody. Or potentially more expensize for everybody ... there are already fees to use certain things, and TPTB have mentioned the idea of having a site fee in the past.

I've sent a handful of PMs like this and of about 6 PMs that I had to send, 5 of the books ended up being marked received (with various themes of "I forgot").

I figure I am doing my part to keep PBS free.

Once again . . . what Sara said 

Your job is not really done yet. You have your credit, but the Help Center does ask that you follow up on it. I usually give them 7-10 days before contacting the receiver. Then if they don't respond within a week, the Team should be made aware of it so they can follow up.  When you use PBS DC you already have your credit, but the site has to cover those lost books so we help keep the cost of Credit Assurance down by following up on those books that are scanned delivered but not marked as such.

If you sent the book with Delivery Confirmation and it has been recorded as delivered by USPS but hasn't been marked received yet:

• Remember that the book could have been scanned as "delivered" at the local PO, before it went to the requestor's mailbox--the actual delivery can be a few days later  Also, the book could have been misdelivered.
  • The requestor should check with her mail carrier about this package.
  • The package could also be at her local PO being held for pickup; sometimes pickup notices left by the mail carrier go astray.
• You should FIRST contact the requestor using the button on the transaction on the Books I've Mailed tab in My Account when a few days have passed after delivery.
  • If the requestor does not respond to your PM within a week, and/or has not marked the book received by a week after the delivery scan, contact us.  We will look into it.
  • If the requestor responds and says she or he DID get the book, she or he can mark the book received one of two ways:
    • if the book has NOT been declared lost in the mail at PBS - from his or her active transactions (on the En Route to Me tab on My Account) as described in How to Mark a Book Received.
    • if the book HAS been declared lost in the mail at PBS - from his or her Transaction Archive (linked from the top of the My Account page)  as described in I received a book that was 'lost in the mail'.
• If you used DC purchased through PBS, or PBS Printed Postage, you will already have gotten your credit for sending the book.

Thanks for the responses.   I know I got the credit, I just don't want the book to be marked as "lost" if the member actually received it.    Thanks Melanie for posting those directions.
