David Nunn, 76, from Kimberley, has been awarded a British Empire Medal for his work in recording the names of those from the county who died in the First World War.
His work has also recently expanded to include fatalities from the Second World War.
He said: “I am surprised, pleased and very honoured, not just for myself for but for the team who have helped me.
“This always seemed to me the last chance to tell these stories, more often than not untold stories, of those who had made the ultimate sacrifice in confronting tyranny.”
Other recipients of the BEM include Jatrupe Binning for services to the community in Tuxford and Suzey Joseph, homeless health clinical lead at Nottingham CityCare, for services to tackling homeslessness.
Kelvin Langford also receives a BEM for services to the veteran community in Newark while Margaret Waring, from Sutton-in-Ashfield, is awarded for services to people with disabilities or social care needs.
