Canning

I've put up some more cans of fruit tonight. This time Cranberry Sauce and Spiced Pears. I've decided to start a canning journal to keep with my stored cans in order to document the specific recipes used and ingredients, etc. I've been labeling the jar lids with the appropriate name, plus the date it was made, but this way I can look back and see what "else" was put in it.

What do you do to keep track of these things?
Do you have jar labels, or write on the lids?
