Everyone is in hoo-ha about public domain content and how it's an easy way to create your own products, and I couldn't agree more. I've sold more then my fair share of public domain material, but I hardly sell it in ebook form anymore.
Why?Well why would I?
I love ebooks, more then any other way to make money online. Ebooks are great, but sometimes it's a good idea to buck the trends.
Everyone is using public domain content and turning it into digital content, but what I've been doing is using various public domain texts and turning them into massive physical products.
The next project I was about to create in this format was a Chess product from text I found at Gutenberg.org. There are 3 or 4 texts in the public domain that are massive in size and as an avid Chess player, I found fascinating, so I was going to create a massive bounded physical product out of these texts.
This isn't hard to do and there are many ways to go about it.You could on the basic scale just print off the public domain texts and put them into a 3 ring binder, you could create an AUDIO CD set with the text or you could create a tutorial DVD using the example chess moves they give you in the text.
A DVD would go down real well and you could sell it for big bucks.****DISCLAIMER****
