Official websites do not use .rip
We are an unofficial archive, replace .rip by .gov in the URL to access the official website. Access our document index here.

A lock ( Dot gov ) or https:// don't prove our archive is authentic, only that you securely accessed it. Note that we are working to fix that :)
