Notes
^The date of inauguration for Mayor John Coyne is not clear. It is clear that his successor, Kenneth Patton, took office in January 2000. References appear to confuse the 1999 election defeat with the day he left office. Most references state that he served 52 years, some from 1947–1999, a few from 1948 to 1999, and others from 1948 to 2000.
^Both sources agree that Klentz was inaugurated in 1944; West Allis gives a date of April 18. West Allis inaccurately gives Klentz's death date as March 1971, whereas the contemporary source cited gives it as March 5, 1973.

"Promising to guide Clifton in unity through what many say will be its toughest years yet, new Mayor James Anzaldi and his six council colleagues were sworn to office Sunday in a ceremony attended by more than 600 residents. The two-term councilman was named mayor by unanimous vote of the council during a small meeting that was later reenacted for the public."
^Fagan, Matt. "Clifton's longest-serving mayor, James Anzaldi, not seeking reelection", The Record, August 31, 2022. Accessed December 18, 2023. "It appears that Clifton may get its first new mayor in 32 years.... He was first elected mayor by council colleagues in 1990, and he has remained the top vote-getter in every subsequent election."
^Smothers, Ronald (13 February 1998). "Thomas Dunn, 76, Longtime Elizabeth Mayor". New York Times. Retrieved 2023-10-15. Thomas G. Dunn...had served as mayor of the largely working-class city for 28 years, but he was defeated in his own party's primary in June 1992. Still, his tenure earned him the distinction as the nation's longest-serving mayor of a city of more than 100,000 people.
