Ferguson's Legislative Record (amendments offered; bills and joint resolutions introduced; motions and resolutions offered; reports; and remarks) and Voting Record (key votes; agriculture; appropriations; defense production act; education and welfare; foreign policy; labor; military and veterans; miscellaneous and administrative; and taxes and economic policy) are crucial to understanding where he stood on the major issues of his day.
Also important to an understanding of Ferguson's career in the Senate are his public addresses, which took the form of speeches, statements, releases, and radio broadcasts.
In the Topical Files subseries, the researcher will find the biographical materials relating to Ferguson's senate career of interest, as well as those items that shed light on the often stormy relationship between Drew Pearson and the Senator (see Coplan, Pearson, and Thomas files). The correspondence and documents found in the Herbert Hoover file reveal a close relationship between the two men, in which Ferguson often times served as a conduit for making public the views of the former president on various topics. And the researcher should also note Ferguson's accounts of his various trips (see Diaries, and Travel).
