I was researching for about two days but still confused. I wanted to see if anyone knew here. I do not want to hire a lawyer, but if I do not figure this out I will just forget about it. Basically I want to make a Publishing company to self-publish my books. The reason being to more link my books instead of having Lulu isbn's. I created a EIN for the US "Ninja Dog Publishing LLC". If I use this to purchase ISBN's and it will be under "Ninja Dog Publishing LLC", what else would I have to do? I read that you would have to register in your state/county as well, and pay a yearly fee to keep it going. If thats the case then I know I will not make the money back from the book to justify the price. I do not plan on selling it off a tellgate or anything, just through the 3rd party sites. I guess I could just self-pub my books under Lulu ISBN and worry about it later. I just wanted an option to link all my books via ISBN. The government sites are not much help since they are pretty vague, especially with bublishing. I do not plan on selling any service or book directly from the site/me, just using the name to link ISBN's. Thanks!
