Sewing Techniques Book

I got a new book yesterday called 'The Complete Book of Sewing' its a DK one and has lots of step by step instructions. Not so much on how to make specific items but more about using different techniques.
Theres a section on doing different kinds of zips, altering patterns, different seams and hems and photos of each step.
Theres also a useful section on fabric types and what they are used for.
I think it will be pretty useful, I suppose you could find most of the information online if you really needed to, but don't you think it's nice to have a book sometimes?
