This was one of my favorite books when I was a child. I think I was around ten when I used to trace the illustrations in pencil, getting every detail before I had to return it to the library. (I'm not even sure why I had to do that, since I was just going to borrow it again anyway.) There was one picture that showed all the parts of the horse, another showed the tack, etc. etc. I traced the pictures and the accompanying labels. ...Until I found the copyright notice in the front of the book. It said that I couldn't copy any part of the book under penalty of law. At first I thought maybe just tracing a few pictures would be OK. But then I read it carefully again and it said "no part of this book..." so I knew it meant the whole thing.
I was angry at them. And I was also scared. I wasn't sure how they would find out that I had copied the pictures, but I had a very strong image in my head of officers coming to our home, knocking on the door and demanding to see my tracing paper images. I'm not sure what would have happened after that - either I or my parents would be taken away to jail, or my parents would have to pay a huge fine. I didn't want to find out. I think I hid the pictures I had already copied (I didn't want to destroy them) and I didn't trace any more.
It's just funny thinking about this years later. How many other things do I and other people not do because "they" might find out? Things that "they" probably never would find out about. Things that don't hurt anyone. I know, there are proponents of IP law who would argue otherwise regarding this example - I don't agree with them, but at least they have an argument. The same can't be said for those who defend things like the war on drugs, local zoning regulations, prohibitions on doing business without approval from the state, etc. etc. How many things aren't happening right now just because people are afraid of those officers coming to their doors?
