If you are not a licensed Oregon attorney and you need to perform thorough legal research (vs “googling a legal problem,” yikes), you have free access to some of the same legal research databases that Oregon attorneys use: Fastcase is one of them and you have remote access to it through your State of Oregon Law Library (SOLL). (Check out their Blog while you’re at the SOLL website.)
You also have free access to NOLO (formerly Nolo Press) databases through the SOLL.
Remember, Google isn’t enough when you have to appear without an attorney before a judge. I recommend consulting an attorney* or a professional law librarian**, but not everyone (or even most) has access to either, let alone both.
