Back in the 1980s, the Human Rights Committee started publishing collections of its case law in a series entitled 'Selected Decisions'. Volume 8 has just been issued, covering the years 2002-2005. You can get it at: http://www.ohchr.org/english/about/publications/docs/sdecisions-vol8.pdf.
Before internet, I found the printed volumes to be extremely useful. I have not been able to find all of the volumes on the website, but perhaps one of our readers can help on this. You can download the volumes. This provides a very convenient electronic collection of the case law that can be searched using key words.
