A follow-up volume,
Greater Gotham: A History of New York City from 1898 to 1919, written by Wallace, was published in 2017 and covered
New York City history for the following 20 years. Initial plans were to have the second volume's timeline go through
World War II, but due to the amount of material, a third volume was announced, initially covering the period from 1920 until 1945. However, because of health issues and vastness of the time period, Wallace wrote the third volume to only cover the period of World War II, skipping the 1920s and the early 1930s.
Gotham at War: A History of New York City from 1933 to 1945 was published in 2025, the final volume in this series written by Wallace. ==Naming==
