SAP EHS module in R/3 version

Dear Experts,

I have two questions about EHS module:

- We are using R/3 4.7, so in order to use EHS functionality I have activated PLM extension. Is there any difference between R/3 and ECC in EHS module?

- The only books in English which are available to buy are three SAP Press.

For the following courses are there standard books or can I buy any other standard book in EHS?
