Communications Consultants, Inc. was founded in 1965 by Duane Nielsen to offer "a complete scope of consulting and audio-visual production services." Records include correspondence; proposals for an architectural preservation documentary about Portland; and materials relating to projects on the Sea Lion Caves and Boston.

Materials collected by World of Speed, a museum in Wilsonville, Oregon. Materials consist of records of automobile racing associations, a tourist brochure map of automobile loop routes in Washington, photographs, and VHS and DVD copies of a 1997 documentary, "From Hellgate to Portland." World of Speed opened in 2015, and permanently closed in 2020 as a result of the COVID-19 pandemic.
