Can somebody tell me where on the sheveles in the saboteur book and where on the upper level is it and how can i find it

I don't know which part of the walkthrough corresponds to where you are in the game, but if you can find where you are in this video walkthrough, it will show you exactly how to find that book. The video walkthrough is in several parts; I gave you the link to the first part, just to help you get started.

im sorry i left out the school library

That's okay. You go to the school library more than once, so try to find in the video walkthrough where you are in the game and when you do, it should be very helpful in showing exactly where the book is located.
