PCB design guidelines !!

Hello all,

At the outset merry christmas to one and all!

I requirement any material - links, e-books, pdfs - that deal with the following topics -
1) Guidelines for PCB design with reference to EMI and EMC.
2) Guidelines for PCB design for hardware mixed signal components - microcontrollers, audio circuits, switching power supplies - focussing on Ground planing

Cheers to all!
