Fonds consists of records created or accumulated by Hugh Guthrie in his capacity as secretary to Progressive Conservative Party South Wellington and as a partner in the law firm Hungerford, Guthrie, and Berry. The records document his involvement in leadership conventions, provincial elections, meetings of the party, and his practice in law. A portion of this fonds is comprised of by-laws collected by Hugh Guthrie pertaining to the City of Guelph.

The fonds has been arranged into four series.
