I'm sure you're also wondering about how exclusive the information would be if it is available for everyone's use
. Well, it isn't very exclusive but if you really want something that's going to be all yours then you can also purchase rights which are going to be more expensive. The prices range from $900 - $15,000 depending on the product but these would provide you with the exclusivity that you need and could also help boost your sales since you would be the only person with that certain information. Again, there's a massive archive to choose from and the opportunity is just too enticing to say no to. You just have to learn where you might find these public domain works and how to wisely re-publish them. After that, you're pretty much set.
