This bibliography is an attempt to list all the publications dealing with helminth of waterfowl (Anatidae) -- reports of their occurrence, descriptions, classification, life history, and pathological effects. It brings up-to-date and revises the work published on microfilm in 1965 (Wildlife Disease, No. 45). Studies on prophylaxis and treatment and on physiology, and general manuals and texts on poultry diseases are omitted. Publications issued before 1890 (numbering about 120) are also omitted as the information in many of these is incomplete and the identification dubious.
