from a "Chart" in Entertainment Weekly, Dec 2009 it says

THE HOBOKEN CHICKEN EMERGENCY Daniel Pinkwater & Tony Auth Readers of this children's book--about a chicken that terrorizes the New Jersey town--might love Pinkwater, but we bet library catalogers think the author's a headache. After all, Pinkwater goes by several different names: His 1998 book At the Hotel Larry was written by "Daniel Pinkwater," his 1977 book The Big Orange Splot was written by "Daniel Manus Pinkwater," and his 1977 book Emergency was written by "D. Manus Pinkwater."
