This volume contains 27 original chapters on British studies in obstetrics and gynecology presented to the Royal College of Obstetrics and Gynaecology in 1995. In the words of Dr. John Studd, volume editor and RCOG publications officer, The Yearbook gives us a unique opportunity to publish some of the fascinating eponymous and historical lectures which deserve a greater audience àIt also allows publication of the best clinical and laboratory research coming from British centres in a way which is easily accessible around the world.
