Bread-Bakers v098.n015.14

I hope someone can help me. I have a Panasonic 1-1/2 lb loaf machine but i've
found some recipes in some of my bread cookbooks for 2 lb machines. How do I
go about reducing the recipe? I'm assuming that i could just halve the recipe,
but am not sure that would really work. Any ideas? Thanks in advance and Happy
Baking!!
