Try the local university library. In the city I live there is some; just go see the Administration for a security pass first to avoid any security issues as a campus visitor. Since state collages collaborate in research; your local state university should have some as well... might want to call it first and find out; if not the largest city nearest public library should have some.
Checking them out in University not really possible unless you are a student however there are reading rooms. Public library offers a card... those can be checked out; but they too have reading rooms if distraction is a problem elsewhere.
Some colleges have their entire library and even college courses uploaded like Harvard has been doing allowing anyone to sit in on classes free as if you were a student since it is "free" it is unaccredited meaning you wont get a degree but at least you can learn it so if you attend elsewhere then it is a great primer to already know whatever it is before you take it.
So going to college library websites might be just the ticket to the quality texts you are looking for.

Just sitting like immersion in shunyata one will be like a cup or bowl and pick up the entire whatever it is like accumulation... if one leaves all formation alone is shunyata as all mental aggregates fall on the potters wheel when the senses are grasped at resulting in moving the mind/turning the wheel; instead of sitting the mind so it becomes filled when that link of becoming makes it's round.
