Xlibris, the book self-publisher believes it will make money in increments. “I’d say it’s around two bucks for each copy of each title. Let’s say I make $600 per title and I have 250,000 titles. Okay, well my calculator just broke, so it’s a big enough number that my calculator’s not happy. I think it’s about $150 million. So, you see, the whole industry only makes sense if you believe that in, say, six to seven years, there will be close to half a million books published every year. We’re doing 500 titles a month by ourselves, and our growth rate is around 20 percent a month. So, you do the math.” – Inside.com
