Satanism in Schools...

To understand Enochian magic, you'll probably want to get familiar with John Dee, Queen Elizabeth's astronomer and counselor (among other things). Dee was also instrumental in the creation of British intelligence and signed letters written to the Queen "007".

There are some good books on Dee and they aren't hard to find. You will also find excerpts from his diaries on the web and in published collections. And if you happen to find yourself at the British Museum in London some day, a small (but significant) selection of his magical tools and personal effects are on display.

For information on the various Enochian systems themselves, you might start with the Wiki page.

Traditionally, information on Enochian magic in the form of decent books has been sparse. I find myself going back to a few in particular, which I'll list briefly - but, again, depending on your personal mindset, you may or may not find these useful or in line with your own beliefs/practices.

Enochian Magic in Theory by Frater Yechidah (Dean F. Wilson)
Mastering the Mystical Heptarchy by Scott Michael Stenwick
Practical Angel Magic by Stephen Skinner & David Rankine

If you want a book that breaks down the magical elements and simplifies much of the archaic terminology, Jason Newcomb's Practical Enochian Magick is pretty good, but keep in mind that the Enochian workings within this book were essentially developed to complement his own system of magic, and some aspects of Dee's system have been dropped to make things less complicated.

If you don't mind a Thelemic bend, Lon Milo DuQuette's Enochian Vision Magick is a good read.

And if you're interested in the Golden Dawn's take on Enochian magic, Israel Regardie's book, The Golden Dawn , contains a reasonable amount of information on how they utilize Dee's magic. The Golden Dawn's version of Enochian magic is unique to the Order and is arguably its own system (they developed it before certain key documents from Dee's library were discovered/deciphered). However, this is also the most well-known application of Enochian magic, so it's often what is being referred to when people talk about Enochiana.

The version that shows up on television shows like "Supernatural" is derived largely from the Golden Dawn's practices. In the case of "Supernatural," the show uses an Enochian alphabet that's easily distinguishable as the one that's used by the Golden Dawn.

A good place to start, though, is the previously mentioned Enochian Magic in Theory by Frater Yechidah. I wish I'd had that book available to me when I started practicing 22-23 years ago.

I'd recommend against Donald Tyson's Enochian Magic for Beginners - at least initially. It contains some good information, but the author spends a fair portion of the first section of the book trying to convince the reader that Enochian magic, in practice, is a tool to open portals to Hell. :evil: Which it's not.
