was a concise yet comprehensive handbook that became an
indispensable tool for the residents of the Harriet Lane Home. Ultimately,
Robert Cooke (department chief, 1956–1974) realized the potential of the
hsandbook, and, with his backing, the fifth edition was published for s
e r wr idsespread distribution by Year Book. Since that time, the handbook has e r r s
k e k e

The Formulary, which is undoubtedly the most popular handbook
section, is complete, concise, and up to date thanks to the tireless efforts
of Carlton K.K. Lee, PharmD, MPH. With each edition, he carefully
updates, revises, and improves the section. His herculean efforts make
r thse sFormulary one of the most useful and cited pediatric drug reference r s s
k e e trexts available. k e e r
