<p>Alan Libert took many photos of public signs while travelling in Altaic areas. These signs can give several kinds of linguistic and sociolinguistic information: 1. Most public signs in the Inner Mongolian and Xinjiang Autonomous Regions of China are bilingual. However, the relative sizes of the writing in the local language and Chinese are often quite different, as can be seen in examples here. 2. There are sometimes other languages (e.g. English) on signs as well. This archive may give an idea of the kind of signs on which this happens. 3. The syntax of the local languages on the signs can be studied.</p>
