Legislative Research at Oregon State Archives

Committee Exhibits

Legislative exhibits are placed in separate files, in conjunction with the minutes, and are arranged by bill number, date, letter or subject. They include written testimonies, proposed amendments, letters regarding bills, reports, measure analysis, publications and related material. Exhibits are submitted by legislators, committee staff, and witnesses.

Committee Minutes and Audio Tapes

Legislative minutes are arranged by House, Senate or Joint committee and thereunder, in chronological order by hearing date. The minutes include date and time of hearing, individuals present, and measures heard. They summarize committee hearings and highlight the major points of discussion. They reflect discussion and testimony by legislators and interested parties on proposed legislative acts. The legislative minutes are not a transcription of the audio tapes.

The legislative committee audio tapes begin in 1957 and consist of reel-to-reel tapes, dictation tapes (1967-69), cassette tapes (1981-2007), and now digital audio recordings. Audio tapes are sometimes indexed in minutes or tape logs. The reference staff will duplicate tapes (except dictation tapes) for sale. There will be an additional speed change fee if a cassette copy is requested from an original reel-to-reel.

Floor Proceeding Audio Tapes

The legislative floor proceeding audio tapes are arranged by House or Senate, there under, chronological by date. They document the House and Senate floor debates during the regular sessions of the Oregon Legislative Assembly. The House tapes begin in 1963, the Senate in 1973. They consist of reel-to-reel tapes and cassette tapes. Tape logs are available for most sessions.

Legislative Holdings

Early legislative records in the Oregon State Archives begin with the 1843 Legislative Committee which drafted the Organic Laws and created Oregon's Provisional Government. Check Oregon Statutes, Laws, and Journals in the Oregon State Archives Reference Library (below) for resources prior to the keeping of legislative committee records (e.g. minutes, exhibits) which are the primary source for finding legislative history.

In the late 1920s the Oregon Legislative Assembly began keeping committee minutes and exhibits. The Archives has minutes and exhibits of the Interim Workmen's Compensation Committee for 1926-27. These records do not become continuous until 1961 when the Oregon Legislative Assembly passed a law requiring the deposit of legislative records with the State Archivist.

Legislative Research

Research in legislative records requires a bill number and year. With only the Oregon Revised Statute (ORS) number follow these steps:
  1. Look at the end of the ORS section where the Oregon Laws (regular or special session) chapter and years are cited in parenthesis. For research of legislative history prior to 1953 look in the ORS, 1953 Reviser's Notes, to find the Oregon Laws chapter and year.
  2. Look up the chapter in the Oregon Laws for that year. The bill number is cited at the beginning of the chapter.
  3. Look at the legislative calendar in the same year's Senate and House Journal. The calendar shows which legislative committees the bill went through. Make a note of dates in committee from the "date of referral" to the "date of do pass." Do an inclusive search through the minutes. Do not depend upon the dates cited in the calendar or in the committee clerk's index at the beginning of most committee minutes.
Check with the reference section of the Oregon State Archives to see if a legislative bill has been researched by the reference staff. Research on 1991, 1993, 1995, 1997, 1999, 2001, 2003, 2005, and 2007 bills are located on this website​.

In addition to Legislative Assembly records other agency records may be useful in researching legislative history, such as records of the Office of the Governor, the Department of Justice, and The Council on Court Procedures.

Original Bill Files

The original bill file (or original measure folder) is a compilation of the original measure with subsequent engrossed versions and, if it passed, topped with the enrolled copy of the bill. The bill file can also include committee reports, printed amendments, history sheets, fiscal analysis and staff measure analysis. The committee report is a daily notice of committee actions on measures. The staff measure analysis summarizes the issues and expected impact of the bill. The engrossed versions of the measure add and delete words, phrases, and sections as they go through the legislative process.
