Ahh, I was trying to imply "easy" read - it stretches from intro into (though slightly dated) 2-3rd year college territory concerning general electronics. But definitely not quick - and it is pretty pricey.
There was a thread a couple weeks back where I was talking about old "intro to electronics" series by Forrest Mimms that used to be sold at Radio Shack. There may be some useful links in there if you can find that thread.
Other than those two "sources" I tend to learn a lot reading the application notes that are available on manufacturer websites - Microchip has quite a few appnotes that deal with pretty general topics, but a interesting place to search for interesting circuits tend to be the analog chip manufacturers - National Semi, Fairchild, Analog Semi, Linear Tech, Texas Inst. If you can dig through their websites, they usually have lots of neat application notes dating from the mid80's to present. They're free, pretty informative, and at the very least, can direct you to different topics.
