[2] Later owners Aden Hyde and F. H. Michaelson sold the News-Tribune in 1937 to a corporation managed by J. T. LaFond, formerly of the Nampa Free Press.

[13] H. W. Mansfield then purchased the Leader, and in 1900 he bought the printing plant of the former Nampa Progress, published by Daniel Bacon until his death in 1896.

[9] The Leader-Herald ceased publication as a daily newspaper on August 28, 1937, although Mainwaring briefly considered operating the paper as a weekly.

[20] Within days of the sale, the Idaho Free Press announced that it would occupy the offices of the former Nampa Leader-Herald.

[21] The Co-Operative Publishing Company of Nampa began printing the Idaho Free Press in April 1919.

[22] Closely aligned with the Nonpartisan League of Idaho, the newspaper was an early supporter of socialist and Progressive Party causes, and marketing favored farmers and workers.

[25] Mainwaring bought the paper in 1937 and remained in charge until 1953, when he sold the Free Press and purchased the Capital Journal in Salem, Oregon.
