D.G. O’May authored Ferries of the Derwent A History of the Ferry Services on the Derwent River in 1988.

The O’May family is well known for their connection with the maritime history of the Derwent River over many decades.  The chapters of the book cover different aspects of the ferries that travelled across and up and down the river, and many old photographs of ferries, key people and historic documentation including licenses have been reproduced.
