I've written a bunch of songs and copyrighted them with the U.S. Copyright Office. Our band has recorded a few and plans to do more of them soon. I'm told that any royalties for recordings are split between the copyright holder and the publisher. I'm also told that it's a good idea to form your own publishing company for your own songs, in order to get all the royalties.

I've been doing some reading on the BMI site: BMI
the Harry Fox Agency site: Harry Fox Agency
and a company that will produce the CD's: Discmakers.

None of them (that I can find, through ALL the verbiage) tell me how to create my own publishing company. Any advice on how to go about it? Is it worth doing?
