Sometimes I get bogged down in research. This happens in one of two ways. Either the answers to the questions are not forthcoming and I spend all my time jumping between sites or I get engrossed and suddenly know more than I ever needed to know.
As a writer I research a variety of things: the United States Navy, the Royal Navy, the New Zealand Navy, nurseries, the effect of a vacuum on the human body, village post offices, the travel time between New Zealand and New York, the average age of a Naval Lieutenant, Police procedures, the Salem Witch tries, explosives, guns, nuclear weapons, and Ford Prefect Cars.
These are not all for the same story. I do wonder though what conclusions someone might draw were my Google searches ever called into question.
