Private Label Rights

Private Label Rights means that the purchaser of the digital product can claim them self as the author and modify/detract/edit the source.  For example, if you purchase an ebook with "Private Label Rights," you will most likely receive it in either Microsoft Word or plain text format.  That way, it can be edited as you see fit.  (Most ebooks without Private Label Rights are usually "locked" somehow, so that you cannot edit, change, or reverse engineer the product.)
