Another one of those must have tools for the "eTeacher"

As a teacher who relies heavily on ebooks as reading resources and reference material for students, I download a lot of ebooks from the internet. One problem I have come across is how do I split the PDF to extract only the pages I want to give the students and leave out the rest.

Rather than copying the entire chapter and pasting to word which I used to do before I decided to do some googling to find out if there is an app that can split the PDF and give me just what I want. (This feature is built into adobe pdf but you will have to register to use it which I couldn't.)
