To an extent, yes, i feel that they are protected but then again today anything and everything risks being copied.
The reason I express myself here is because I do not have the right resources (read billions of dollars) to get a book marketed and sold after publishing... When I was 13, I did publish a book but it is all about knowing the right people and how much money are you willing to give them.
There is barely a market for book readers in Pakistan and publishing houses prefer to publish people who will give them Millions.
Hub pages gives me an unbiased outlet, where people choose to read my material because they want to and not because they have their own personal benefit attached.
