I generally recommend that residents who want a book look at:
Neonatology : Management, Procedures, On-Call Problems, Diseases, Drugs (LANGE Clinical Science)
by Tricia, Lacy Gomella (Editor), M. Douglas Cunningham, Fabien G. Eyal, as a pocketbook that is very complete for resident use.
Care of the High-risk neonate by Klaus and Fanaroff is a more classic textbook but I think most residents will do better with the other book.
