AoE, Machinery's Handbook etc are wonderful references, not for learning. “Make: Electronics” by Charles Platt and "Practical Electronics for Inventors" are both good practical recommendations. What to prefer really depends on your background. I'd add "Electronic Devices" by Thomas L. Floyd if you prefer more academic/systematic approach.
