Periodical literature played an important part in the rapid and widespread dissemination of Millerite beliefs. "From first to last the power of the press, in this particular form, was one of the foremost factors in the success of this now vigorous, expanding movement." In addition to the "Signs of the Times" based in Boston, Millerite papers were published in numerous cities including New York City, Philadelphia, Rochester, Cleveland, and Montreal, Quebec. There were at least 48 Millerite periodicals that circulated in the period leading up to the Great Disappointment. The majority of these, however, were quite short-lived—often a new paper was started whenever a Millerite evangelistic campaign entered a new area.
