Thanks in advance for any and all recommendations!
These books are easy to read and understand and they feature color pictures. Each book covers a different subject ie. Basic Electrical, Advanced Electrical, Plumbing, Masonry, Decks etc.
Accumulating these books costs more than buying a single book (eg. Home Depot's - Home Improvements 1 2 3) but they go into much greater detail and I've found them to be more useful.
For electrical work I also have a copy of the National Electrical Code, and I have my eye on a related publication that is essentially a commentary on the NEC.
