Lisa,
You've received a number of good suggestions.... Other possible temperance
newspapers (though more difficult) sponsored by national organizations
include:
Journal of Humanity and Herald of the American Temperance Society
Templar's Magazine
The International Good Templar
The National Temperance Advocate
Of course, there were plenty of other nationally-distributed periodicals
that included temperance news, like the religious press (Christian
Advocate) and even secular journals like The Nation.
Good luck!
