Thank you for this, Alex. I think you are absolutely right and I have to say, this is where I get into trouble because I have a very hard time formulating a purpose. I can only come up with vague ones, like I really want to understand what is in this book, which is really ridiculous. So, you are right!
I don't think I even got the previewing down, because it does not help me with coming up with a more specific purpose. Do you have any ideas for me?
