sdeepakraj, Read the information section on how to get Reputation. It might seem a hassle to newcomers but it's very easy. Once you have few reps you will be able to download most of the books you are searching for including notes.
You won't find the latest edition book anywhere else.
Will be posting more new editions of Nutshell Series by Capt.H. Subramaniam., Probably in August after international flights reopen.
