The  most valuable and essential tool to the witch is a  BoS (Book of Shadows). This  is a collection of all your learnings,  memories, rituals, etc. in one place.  Most modern Wiccans use  a three-ring binder to make it easy to arrange documents  and add  in other papers. This can, of course, be hand-written or printed from a computer.

The following  is  a listing of some common things people keep in their BoS. Don't  limit yourself-  just because these are the most ordinary things  to keep, it doesn't mean they  are the only things you  can keep. Creativity will make your BoS more  special.
The  Wiccan Rede
Include a copy of the rede. You may  also  want to have an evaluation of the rede- that is, "dissect" the rede  and  consider each statement, and write about its meaning and value  to your  practices. Our copy of the rede can be found here.
The  Sabbats
Have a copy of the eight major sabbats  and  include information on the importance of each one.  
Calendar
A  calendar of the moon phases, progressions,  and the astrological  signs they are in each day. Mark new moons and full moons.  Also  include major events, holidays, and sabbats.
Magickal  Correspondences
A list of what each god and  goddess  represents, and a list of the meanings of herbs in magick, and the  symbolism of different candle colors. Maybe include a list of  the significance  of different scented incences.
Rituals  and Spells
Have a section of rituals and  spells you  find practical and useful, or you may need for future occasions. 
Chants and Poems
Chants  or prayers you find  especially nice are good for your BoS collection.  Also, personal poetry and your  own hand-written chants would be  a great addition to your book. 
Daily  Journal/ Dream Journal
A journal of daily  events and  occurences is always a good idea. A dream journal is also an  excellent  suggestion- recording and analyzing dreams can help you to become  more  in touch with your "third eye", or psychic awareness.
Insights
Your  path to learning can help you more in  the future if you are able  to look back on it. Ask yourself questions, and write  your responses  in a section of personal insights. As opposed to a daily journal,  this will not record actual events, but instead, will help you  to reflect on  theories and thoughts. Think about how you began  on this path, reconsider your  ways of life, think about the wonders  of reality, write a little on what Wicca  means to you and how  it's changed your outlook on life. Anything goes. And you  can  always return to a previous insight, and add what new views you've  stumbled  upon! Don't forget to write the time/date on each  entry!
Remember,  don't just stick a bunch of stuff into your BoS. Only  include  what you consider to be of value, and always make your own alterations.  If you put a ritual in their, write side-notes on what you decided  to change for  your purpose. If you put an inspirational article  in there, add your own  thoughts and ideas in the margins. But  remember on thing this is your BOOK OF  SHADOWS...
