During the days of early Ohio history, it served as a stagecoach stop, then later a railroad town. The Toledo and Ohio Central (T&OC, later known as the New York Central Railroad Eastern Branch), and the Cleveland, Akron, and Columbus (CA&C), later known as the Pennsylvania Railroad Akron Secondary, used Centerburg as a rural stop during the peak of passenger train travel in the US.
The Centerburg Local Schools have recently gone through a major makeover in the facilities. A new high school/junior high school campus was opened in 2003. The existing elementary campus also went through renovations. The mayor's office and council currently use the recently renovated Masonic Temple as city hall. In addition, the Centerburg Public Library is one of the oldest independent libraries in Central Ohio.
The Old Time Farming Festival, the Centerburg USA 4th of July Festival, and the nearby Hartford Fair are major events for people in the area.
The village and Hilliar Township is protected by the Knox County Sheriff's Department for law enforcement. The Central Ohio Joint Fire District takes care of fire and rescue duties with Hilliar, Liberty, Milford townships in Knox County; as well as South Bloomfield township in Morrow County and mutual aid to other parts of Central Ohio.
 Notable residents
 Publicity and media
In 2009, the Centerburg Local School Board voted to cancel that year's graduation ceremony in response to a cheating scandal, even though only one person out of the entire 97-student graduating class was ever proven guilty of cheating. Parents and students responded with a protest at the high school which was ultimately televised and broadcast nationally in the United States. Ultimately, the parents and the Centerburg community came together and held a graduation ceremony for the graduating class at Hillar Park. Television stations in nearby Columbus covered the unofficial graduation ceremony held at Hillar Park. Footage of the protest and ceremony were also broadcast nationally on CNN. Despite voting to cancel the official graduation ceremony, every Centerburg school board member who was up for re-election in 2009 was re-elected, despite none receiving more than 30% of the total vote.
