I like:
Nuts-n-Volts (
http://www.nutsvolts.com/) (USA)
Everyday Practical Electronics (
**broken link removed**) (UK)
Servo Magazine (
http://www.servomagazine.com/) (USA)
Any ham radio magazines: Practical Wireless etc. These have all sorts of electronics tidbits and gems.
I like the Tab book Teach Yourself Electronics (**broken link removed**) Note that this book includes a lot of examples which might require extra components (usually capacitors, it seems) to work in the real world.
If you're really keen, the Art of Electronics (Horowitz & Hill) is a good one. It's pretty intense but has the benefit of being unambiguous and thorough. If you really want to know about how to build a temperature-stable amplifier or how to size a heat sink, this will help.
Hanging out on forums like this and reading what some of the more experienced folks have to say is also very, very helpful. If you have questions, make them complete and include details of what you're trying to do.
For Usenet (these days, AKA Google Groups), sci.electronics.basics has a lot to offer, or at least has had. The signal to noise ratio can be pretty high nowadays. (

The ". . .for Evil Geniuses" books are fun, but seem to require you to order special pieces from the author to build the projects presented.
If you have access to a Radio Shack or other source, anything by Forrest Mims is a good reference. Dont expect to build, say, a great radio from the "Engineer's Notebook" series, though.
