For beginners 3D STUDIO MAX for dummies is the best

 

3D max is one of the most fluid 3d modeling program I have ever dealt with. in regards to learning in my opinion websites/online is better than most books, for the following reasons:

1. you can access the website at anytime, how many time I was in the office and needed a reminder on a certain task and the website saved the day.

2. you can save the pages as references for later.

3. if the website provides videos, thats even better. first hand exercise stays in the mind than a read book.

there are many more, but in short websites are more convenient.
