100 Power Tips for FPGA Designers

Great initiative Guillermo, we will all benefit from this list of resources.

I like to read books, it keeps me away from the computer for a while and I can read them anywhere. I am now reading this book, A Hands-On Guide to Designing Embedded Systems, by Adam Taylor, and discovering how difficult and fascinating the job of an embedded systems designer is. 

ARTECH HOUSE USA : A Hands-On Guide to Designing Embedded Systems

I echo the recommendations for Adam Taylor. You can also find Adam on these two sites:
