It’s pretty rare that I come across a free book with so much good information in it, but Analog SEEKrets is definately worth a few days of any budding young engineers time.  Written by someone who clearly has enough years experience behind them to know what they’re talking about, this book — freely downloadable in PDF format — contains a lot of excellent real-world information that anyone working in the commercial world will either recognize or appreciate.  Some of the practical things I liked in the book were checklists you can give to any new team member, such as the Pre-Supervisor Checklist (p.19) to make sure someone did their homework before pushing problems up the food-chain.  (Helpful Hint:  If you want to fit in well in any engineering team and get the help you want when you need it, it’s important to make sure you’re not asking questions you could easily have solved yourself, or at least be able to demonstrate that you’ve clearly made some effort first.  I wish I would have thought of making a list like this myself working with interns, etc., as they tried to learn the ropes to make sure everyone is getting the most out of the time available in the average working day.)

There’s a lot of excellent information in this book whatever your experience level, and it’s well worth downloading and reading.  If you find it valuable, definately consider making a contribution to the author to thank him for making the book freely available online now that it’s no longer in print.
