From online dating to scholarly collaborations, the web facilitates millions of interactions between distant groups of people every day. One question recently posed by the United Nations Educational, Scientific and Cultural Organization (UNESCO) was this: What languages are being used in all of this online activity? A good question to be sure, and this important document is the result of their lengthy inquiry. Published near the end of 2005, this 106-page paper contains a number of important findings about the nature of researching linguistic diversity on the internet. The paper includes sections on the usage of Asian and African languages on the internet, along with an investigation into linguistic bias authored by John Paolillo. The report is rounded out by a very thorough bibliography that will be of great use to those with a detailed interest in this area.
