Could this be the first edition of Dr. Ruth Lawrence's "Breastfeeding:A guide for the medical profession" or could this refer to Riordan and Auerbach's "Breastfeeding and Human Lactation" I own Dr. Lawrence's "blue book" (third edition, I believe) and at the WIC office we own the "red book" (latest edition)" Oh, yes, we also have Riordan and Auerbach's "brown book" Sweltering in Brooklyn, Pearl Shifer, IBCLC
