Type of Spell or Formula: This should state very clearly what the type of spell is, for example, blessing, binding, and so on. When developing formulas for lotions and potions, for instance, you need to be clear as to the exact purpose.

Date and Time Made: This gives a cross-reference should you wish to use the correct planetary hours or magical days.

Reference: You should develop your system of reference; this might be, for instance, according to the time of year or alphabetically.

Do also remember to keep safely somewhere a record of how you have developed your reference system, so that others may benefit from your experience.
