Their first three books were Trails with Tales, Adirondack Trails with Tales, and Paths to the Past. Hudson Valley History Hikes is the fourth book in the series. The fifth book in the series, Capital Region History Hikes, will be published by Black Dome Press in 2025. Barbara and Russell are retired New York State–licensed hiking guides.

He has also published a series of anaglyph 3-D books. Barbara Delaney has become well-known for her two books of fiction, Finding Griffin: An Adirondack Novel and Follansbee Pond Secrets.
