A Reference Guide to the Big Book
of Alcoholics Anonymous
by Stewart C.
An actual index or concordance to the Big Book
Great for research or just checking things out.
The Varieties of Religious Experience
by William James
Deep, rich and important to the forming of 12 Step
spirituality - worth the effort.
Many
Roads, One Journey
Moving Beyond the Twelve Steps
by Charlotte Davis Kasl
A truly awe inspiring
book which contributes much to 12 Step thinking. Not light reading, but
perfect for dipping into and exploring. Kasel offers an alternative set of
steps I find too long and complicated, but the rest of the book is
wonderful. I strongly recommend this book!
How Alcoholics Anonymous Failed Me 
An unhelpful whine.
Interesting if you're doing research or want a way to avoid a 12 Step
Program, but disappointing for many of us.
The Handbook of Nonsexist Writing
by Casey Miller and Kate Swift
Out of print, but Amazon will get it for you in about two weeks - worth
the wait!
