There is one box of correspondence containing both incoming and carbon copies of outgoing letters. In many cases the reply has been stapled to the incoming letter. The letters are concerned with the business of running a newspaper, Bottolfsen's positions as Governor and state senator, his position as parliamentarian for the National Education Association. The only personal letters are copies of letters written between May and June 1963 when Bottolfsen was being treated for emphysema in the Boise Veterans Hospital. Correspondence can also be found throughout other series.

Letters are in chronological order; where more than one letter was written on a single date the letters are arranged alphabetically by correspondent. A card file has been prepared giving addresses of correspondents, dates of all letters, and in some cases the topic discussed. Names of correspondents have been included in the finding aid. Topics include: Idaho. Legislature. House of Representatives. H.B. No. 74. Repealing the Senior Citizens' Grants Act. 1943. 2 p. Idaho State Committee of the Communist Party. "Who is Responsible?" Mimeographed sheet. January 1943. 1 p. Proposed Initiative Petition: Senior Citizens' Grants Act. Nov. 1942. 4 p. Summons. In the District Court of the 3rd Judicial District of the State of Idaho in and for Ada County. Orlando A. Scott (et al.) vs. C.A. Bottolfsen (et al.) A suit to test the constitutionality of H.B. 74.

There is one folder of letters dealing with the Senior Citizens' Grants Act. In November of 1942 the people of Idaho voted overwhelmingly to approve a bill granting senior citizens an income of $40.00 per month, plus limited medical and dental coverage. In January of 1943 the Idaho House, in H.B. 74, voted to repeal this act, the senate confirmed the house action and the bill was sent to Governor Bottolfsen. He reluctantly signed the repeal on February 6, 1943, saying there was just not enough money in the state treasury to finance such a measure.
