One of the things that each of us has, as a Wiccan or Witch, is a Book of Shadows. Some people keep theirs shrouded in secrecy, in the fashion of more ceremonial magick. Some of us are more open with them, using them as a tool in the education of non-witches or new witches.
When I first found Wicca, I had my BOS on the computer. Or more accurately, on several *wince* floppy disks. Yes, floppy disks. They were colour coded and everything. I slowly transitioned to a journal, because I enjoyed having a portable BOS. That didn't last long, however. I quickly realized that if I had my BOS in a journal I couldn't re-arrange the pages if I needed to, or decided that I should add an extra page on to the section on herbs or add just one more healing ritual in. So I switched back to a computer, but only to type everything out and print it off. I've had my BOS in a binder for many years now, and with page protectors I don't have to worry about the pages ripping out or spilling candle wax on the pages during ritual. And if for some reason a page does get ruined or lost somehow, I can always print out another one.
I use a lime green binder, but I painted a moon Goddess on the front of it myself. I really like the binders that have the insert in the cover, so you can just put something in and have it personalized just like that. As a Hearth Witch, I always have to have a section for Sabbat recipes. I have a section on healing and protection. And then I have the "normal" stuff as well.
In the world of constant connection, you can find pretty much everything you need in a Book of Shadows online as well. How many witches of the new generation are going to have a traditional Book of Shadows instead of just finding what they need online and the drop of a hat? Or even *shudder* using an "app" to find a ritual.
What do you use for your Book of Shadows? Do you still have one?
