Diablo is 100% correct. Simply getting your hands on a book as your original question inquired about is pointless. You need that book to be processed by whichever organisation got it approved by casa in the first instance.
I am unaware of any 737CL ojt books having been approved but you can check AC 147-2 to see.
Regardless, unless the organisation (145 or 147) will process the book for you then it is worthless.
Sorry.
