I have a question. The instant download "Eye of the tiger", who does that belong to, Penguin? Nope, it can be found in a very common magic book. Penguin is porfiting from someone else idea, right? So, wouldn't they be stealing. Or as one person posted "exposing something is steal". By that persons definition aren't they exposing that trick? Not that i have a problem with that or penguin. I was just making a point. Also, Magic books are exposing magic secrets, thats whay they are made to do. The authors of the material whether its original material or not, do not care about who reads the book. They care about the money it will make them. Magic used to be like an apprenticeship, passed down from master to worthy student. The information disclosed to the pupil was done so because the master felt as if that person was worthy of that knoweldge. Putting magic tricks in books / dvds and putting out for the whole public to see, magic and laymen alike, says that you care more about the money it will make you then upholding the magicians code. Remember at one point you were a laymen, and someone or dvd or tape or book exposed the methods of our art to you. Without some form of exposer the art would die out. Thats just my opinion

. Also, the book isn't going to stop the author from publishing the book nor would any legal action be taken. The first amendment covers their right to publish what they wish. If you want a case study that illustrates this. Just look at Larry Flints many supreme court battles envolving the material of his magazine Hustler.
The thing is Penguin has probably purchused the right to sell that trick to any who wish to buy it. The difference between penguin and the author is that the creator has given express permission to the one who sells it to sell. chew on that for a while
