Ten top-class teachers in obstetrics have been brought together to collaborate on a brand new edition of the best-selling volume Obstetrics by Ten Teachers. First published in 1917 as Midwifery, Obstetrics by Ten Teachers has been a favourite with students, lecturers and practitioners for many generations, and once again should serve the reader well through their final year exams, and beyond. Along with its sister volume Gynaecology by Ten Teachers, these 19th editions will retain many of the highly-praised features of the previous editions, whilst providing completely new coverage in many subject areas. The two volumes have been carefully edited to ensure that they provide a comprehensive and complementary package for a new generation of students.
