…… or by begging … :)

The nearest university that has a reasonable library is about a 6 hour round 
trip drive. That by its self is not the main problem. 

I’m not going to blend in as a “typical looking student” if I start wandering
around poking at things. I’ve already have empirical evidence that there is about a
90% chance of getting asked “may I see your ID?” as I walk through the door. Fortunately
that was back a bit when I *did* have an ID. Yes I could sign up for another course
and remedy that situation. Yes there may be other universities with more open policies. 
I have not found one around here.
