Grimoir, Book of shadows

Does anyone here keep a personal diary, Grimoir, book of shadows or anything of the sort that they use to store spells, rituals, demon sigils, Pictures or anything of the sort. I am curious to see what others peoples means are in ritual settings and in Satanism in general. Tell us what you do, do you have a book, folder, do you store spells, write a diary, store sigils etc.

I have one full book of shdows that's I call the book of demons It has all the facts and sigils for each demon. I also have another one I call the black book of meditations which has all my meditations in it from void work etc etc.

WOW that does sound interesting i did used to have a personal diary for storing ritual outcomes but then decided to get a foldr where i now store demons sigils, my own created rituals, anything useful to my self that i can use it rituals and of course a place ican store the names of my demon guides, dowser names etc.
