It is doubtful that obstetricians today could take the time to keep meticulous records of each obstetric case of their career, but Dr. Robert B. Elderdice did just that. Inside the front cover of his ledger he wrote "attended my 1st case at age of 21." His ten - column register listed case number, age, name (birth mother), number of labor, date, sex, PPn, fee, remarks, and pay in the doctor's consistently-legible handwriting. (For an illustration of Dr. Elderdice's handwriting, see the vaccination certificate in Appendix 1.) [excerpt]
