So according to what I was told on here, ring bound loose leaf books can be posted on PBS.

BUT when I tried to post a cook book just now, I got this message: "This ISBN matches a book type that cannot be posted on PaperBackSwap."  It is for a ring bound, loose leaf book, America's Cook Book 0684101262.

So can you or can you not post ring bound, loose leaf books on PBS. And if you can, then why is it preventing me from posting the cook book?

I think you should ask PBS to be sure by using the Contact Us link at the bottom of the page. There may be a difference between ringbound and ring bound, loose leaf. The other ISBN that you posted is postable (I just tried it on my shelf), but I was not able to find this one in the PBS database.  When you said ring bound, I was picturing something like this:

In your previous post I was visualizing the ringbound the same as Sarah. But I also have a cookbook, Better Homes New Cook Book,which is looseleaf notebook style, and there is no an error message when I try to post it. The system classifies it as hardcover, but the ISBN is clearly binder/looseleaf if you look it up on Amazon/Google. So I concur, it would best to contact PBS about that particular book and see what they say.

I did find another version of your title posted as a non-ISBN here at PBS. It indicates hardcover, but does not clarify ringbound. The Amazon version appears as both HC and RB, but the HC only has an ASIN.

From Amazon:

ASINs
Amazon Standard Identification Numbers (ASINs) are unique blocks of 10 letters and/or numbers that identify items. You can find the ASIN on the item's product information page at Amazon.com. For books, the ASIN is the same as the ISBN number, but for all other products a new ASIN is created when the item is uploaded to our catalogue. You will find an item's ASIN on the product detail page alongside further details relating to the item, which may include information such as size, number of pages (if it's a book) or number of discs (if it's a CD).

ASINs can be used to search for items in our catalogue. If you know the ASIN or ISBN of the item you are looking for, simply type it into the search box (which can be found near the top of most pages), hit the "Go" button and, if the item is listed in our catalogue, it will appear in your search results.

I get the same message when I try to post most MP3-CD audio books, and those are postable here. So that message definitely does not mean they aren't allowed here.

The problem may be with the term "loose-leaf". Unbound pages aren't eligible for Media Mail, and can't be posted here. Perhaps the "loose-leaf" designation mistakenly puts it into this category. If your book is ring-bound, then you can post it without an ISBN.

Thanks, Patty. The sewing book is a loose-leaf book so even though it is in the data base, it is not postable?

The cook book is a regular hard cover so, since the ISBN in the data base is for loose-leaf, I would have to post it without the ISBN. But I decided, after all not to post the cook book.

But I would like to post the sewing book.
