Prompt: Book of Shadows

This was a suggestion by one of our regulars, and it will surely bring a wide range of answers.....

What is your Book of Shadows/Grimoire like?
Is it digital or hand-written? A spiral bound notebook, loose leaf pages in a binder, or in a handmade binding?
What kinds of things do you keep in this book, and what things do you leave out or reserve for another book?
If you are willing, perhaps take a picture or two to share with us.
How do you ensure the safety of this information? Where do you keep it?

Alright, that's plenty of prompting questions - take one or all and run with them!
Next week's prompt is Samhain, so get your holiday juices flowing! :)
