These files also contain various committee and staff reports on a bill. These reports and bills are held separately in the bill file and are not available in the regular committee files. When researching a bill you will need to specifically request the bill file from archive staff.
While listening to or reading legislative materials you may come across references to various ad hoc committees. The Oregon Legislature sometimes appointed special committees to study and report back on a particular issue. These published reports are generally held by the Oregon State Library and not The Oregon State Archives. You can search for these reports in the State of Oregon Library Catalog.
If a bill or constitutional amendment was enacted or referred by a voter initiative then you can check the measure summary from the contemporaneous voter pamphlet.
