Oregon Administrative Rules (OAR):
1) Current Oregon Administrative Rules (OAR) are online and in print at many libraries.
2) Superseded OARs: Some are online from subscription databases. (See also, the NOT ONLINE list of Oregon legal research resources.)
3) Superseded editions of the OAR are also in print, but only a few libraries have archives all the way back in time.
NOTE: The print OAR Bulletin ceased publication at the end of 2009. Archives does maintain the original filings and users can request copies of specific sections through their reference room as needed.
