I posted this book today: http://www.paperbackswap.com/book/details/9780385737197-Hurry+and+the+Monarch

It's there on my bookshelf and from there I can go to the listing, but when I search for it using the keywords or title, only the hardcover edition comes up. There are no typos in the listing that I can see.

Not sure why that's happening, Willa, but if it's any consolation, when I go to the hardcover listing and click on the author's name to see other books by that author, the paperback version shows up as "available" ... so your edition is at least getting some possible exposure to searchers that way.

I tried too...

Only thing I saw was that the publication  date was listed as 2 - 10 - 2009, so maybe the system won't allow it to be "shown as available'" until after the 10th???

One thing you can do is go to the hardcover page of that book and tag it with "paperback ISBN #_ _ _ _".  this might help until the search catches up with it

Willa, I just searched by title and description, and the paperback came up--in fact, ONLY the paperback came up!

It is working now. I'd guess that only the PB came up because you were searching for posted books only.

I don't think the publishing date can be the reason it wasn't working, because I've searched for books that weren't published yet plenty of times, and found them.

Oh well, at least it's fixed.
