Foss: Ninety Years of Towboating (1981), Mike Skalley
This definitive history was written by the Foss Maritime Company historian and manager of Pacific Northwest customer service. It was updated in 1999 in conjunction with Bruce Johnson and published under the name Foss Maritime: A Living Legend. Several Foss family members (Sid Campbell, Drew Foss, and Pete Campbell) were consulted in the books' assembly.

The book is available in most regional libraries and can be purchased online from several sites.
