Search Monitor Project: China

From Internet Censorship Explorer:

Search engines are increasingly censoring their results, often by geographic location, having a significant, negative impact on the right to freedom of expression. The most advanced cases of censoring political content is in search engines that market a version of their product in China. This project aims to expose and monitor the censoring practises of search engines with a specific focus on China.

Building upon efforts to assess the level of transparency (reading this first is probably a good idea) with regard to search engine censorship, this project aims to compare the level of censorship across the China-specific search engines of Google, Yahoo, and Microsoft as well as the domestic Chinese search engine, Baidu. The goal of comparison poses some significant methodological problems as the presence or absence of censorship notification, mechanism of censorship (and irregularities therein) and physical location of the servers themselves all add additional layers of complexity.
