The remit for contributions to the latest edition is simple: early memories of the city told from a personal perspective, written up in 500-2500 words, ideally including any relevant family photographs.
Ms Brown said people shouldn't be put off contributing just because they were unable to remember small details.
"I don't want the facts, I want how you felt. Anyone can check up the facts on Google.
"These are memories, not a history book. We have got marvellous historians in Rotorua - but this is a social history. I envisage schools using it ... it's making Rotorua's social history available to everyone," she said.
"It was pointed out at the launch of Rotorua RETROone that the collection was mainly non-Maori. It would be really neat to have more recollections from Maori."
In a previous job working at a newspaper in Franklin District, her Just Folk column was dedicated to telling the stories of ordinary readers.
Although she hoped to have the latest edition ready for an August launch, she did not want to rush those thinking of contributing. "It will drive as fast as the people in Rotorua want it to drive."
