It was founded in 1969 as the Mansfield & Sutton Observer. From 1985 to 1987 there was a local edition for Alfreton.
It was published by the Johnston Press-owned North Notts Newspapers, who also publish the Mansfield Chad series of paid-for weekly tabloids. (In fact, the Observer didn’t have a website of its own; the link below is for the Chad‘s website.)
It came out on Wednesdays.
It ceased publication at the beginning of October 2012 along with three other Johnston Press freesheets in the South Yorkshire/North East Midlands area, as the result of a decision by JP to focus on its paid-for titles for the area.
