This is, by far, the best breastfeeding book out there - The Nursing Mother's Companion by Kathleen Huggins.  It has amazing tips and tricks to help new mothers.  It has chapters as well as "Survival Guides" for : The First Week, The First Two Months, Months Two Through Six, Months Six Through Twelve.  It even has a section on Preparations During Pregnancy and an Appendix on Drug Safety during Breastfeeding. Includes discussion of treatment for common problems as well as tips for expressing.  It is well worth reading and very practical.
