Though I don't use much for spreads, here are a list of some of the ones from books I own.
From The Dreamer's Journal:
Astrological Spread
"This spread is based on astrological charts used to plot horoscopes. It is a circle divided into twelve sections called houses. Each house represents an aspect of a person's life. This spread represents you at the time you do the reading. Many people like to do this reading once a year, either at the beginning of a new year or on their birthday."
1)Your self-image and personality
2)Your value systems and material resources
3)Your siblings and communication
4)Your parents, your home, and family
5)Creativity, affairs of the heart, fun, and children
6)Work, responsibilities, and health
7)Partnership, both romantic and business
cool Sex, death, and shared money
9)Travel, higher education, spiritual connections
10)Your public image, vocation, and ambitions
11)Friends, hopes, goals, and wishes
12)Your inner self, dreams, secrets, the past

Two Paths Spread
"If you are facing a choice between two options, this spread gives you lots of information to help you make the best decision. Cards 2,3,and 4 represent choice A and 5,6,and 7 represent B"
----2 3 4
1
----5 6 7
1)Where you are now
2 and 5) The benefits of each choice
3 and 6) The downsides of each choice
4 and 7) The probable outcomes of each choice

I will post more later
