Second, I'm very happy, as a mere hour or so of research turned up the exact text of Oregon and California adoption law, and another hour on Lexis-Nexis should turn up everything I could possibly want for that part of the question. Then all I have to do is a cursory book search for the other facet, and go through the DIALOG citations again and find the ones I need to see the full text of. Which shouldn't take too long.
Edit: Reading state code for two hours on end is very, very exhausting. Especially on a total of seven hours of sleep for the last two days. @_@
