[liberationtech] ONI Summarized Global Internet Filtering Data Now Available for Download

Hi Will,

Thanks for your interest in the data and questions. To clarify this data
does not include testing in US libraries or educational institutions in
the US, as the overview data is intended to document the depth and
breadth of national level filtering regimes rather than institutional
level. Also we do not test for child pornography content in any country
due to legal and ethical restrictions.  Because we have not collected
technical data to verify the depth and breadth of child pornography
content filtering or filtering in libraries and schools in the US the
social filtering measure is rated as no evidence.

While this data release is focused on national level filtering, research
into institutional level filtering in schools and libraries is an area
of interest for the ONI, which we have explored.  For example,  our
latest edited volume Access Contested: Security, Identity and Resistance
in Asian Cyberspace includes a chapter on institutional level filtering
in the Philippines "Competing Values Regarding Internet Use in  'Free' 
Philippine Social Institutions"  by Erwin A. Alampay, Joselito C. Olpoc,
and Regina M. Hechanova. The entire book is available for free download
from the International Development Research Centre here (and will be up
on very soon): 

All best,
