Boss Whistle: The Coal Miners of Vancouver Island Remember

In 1980...[the author] was approached by Nanaimo's Coal Tyee Society to write a book based on 105 interviews of Vancouver Island coal miners and their families. Nanaimo coal mines had closed 30 years before and the city had been home to some of the most important coal mines in the world, along with the one of largest explosions in history, the 1887 Nanaimo mine explosion. The miners wanted their oral histories preserved. Bowen compiled those oral histories in her first book, Boss Whistle, and later book, Three Dollar Dreams. --From Wikipedia article on Lynne Bowen
