Question, “How many ISBNs should I buy?” OK, it used to be…I mean one…I mean we came…a couple of years ago, we came up with this license to sell single ISBNs on behalf of R. R. Bowker at SelfPublishing.com and if you’re only going to…you need a different ISBN for every different edition or type format that you put the book in. It used to be the self-publisher would have a paperback format. That was the way they go. A single ISBN was OK. When you look at what’s going on now, today with the ebooks, OK, especially, you need a different ISBN for each one. So you’ve got a paperback book, ISBN 1. You’ve got an ebook, that’s a mobi which is on Amazon, ISBN 2. You got an ebook which is an epub, which is like everybody buy on Amazon, that’s an ISBN 3. So the minimum I would say, now, is to buy 10. It only cost you like $275.00. You can go to (1:00) SelfPublishing.com, you click a link and it takes you right to the shopping cart there at R. R. Bowker. I think it’s like $275.00.
