Having received and viewed a recent copy of PA's contract (one of several I have received over the years), I can state that PA takes all the publishing rights they can even though they may never use those. Forget selling your book to an overseas market like you can with a traditional, legitimate, royalty-paying publisher offering more than a token one-dollar advance. Those rights are taken by PA for that one-dollar advance.
Like I've stated before, PublishAmerica has a poor contract. Strongly not recommended.
