OHCHR also considerably increased the number of publications available on its website. 1. Fact Sheets 8.

The goal is to help readers understand basic human rights and the international machinery that has been established to promote and protect them. All Fact Sheets are available on the OHCHR website, thereby contributing to their dissemination, a reduction in print runs and a rationalization of costs. 9. During the reporting period, Fact Sheet No. 15 (Rev.1), Civil & Political Rights: The Human Rights Committee, was issued in Arabic, Chinese, English, French, Russian and Spanish; Fact Sheet No. 24 (Rev.1), The International Convention on Migrant Workers and its Committee, was issued in English, French and Spanish; Fact Sheet No. 30, The United Nations Human Rights Treaty System: An introduction to the core human rights treaties and the treaty bodies, was issued in Chinese, English and Russian. 2.
