I love these Moleskin books!  They cost a bit more but they are so flexible and can be used for almost anything because they are not "address book" formatted.  They are alphabet divided and lined but not labelled for entries.  I use mine to keep track of my crystal and mineral collection.  They could be used for almost any list you need to organize.  There is a smaller size available as well that easily fits in a pocket or purse.  I also love the elastic band to keep it closed and the attached bookmark.  Classic construction.
