I prefer my appointment books to open up to a week at a time, Monday through Sunday, not to have Saturday have less room to write into than Monday through Friday, to be dated (but if I wasnt starting my business in January I would start with an undated one), and to have quarter hours.
I like the larger books, I dont carry it around in my purse, so large is great for me. The larger ones have more room to write in as well.
I dont keep addresses with my appointment book. I have too many clients to keep all their addresses in it.
