古音小鏡
A site that even specialists in Chinese praise highly — probably the richest search tool in the field anywhere online. It gathers the classical texts and other materials needed for Chinese historical linguistics: rime-book and character-dictionary search, Chinese dialectology, historical phonology (reconstructions by fourteen scholars for Middle Chinese and seven for Old Chinese, rhyme data from the Shijing, Sino-Japanese, Sino-Korean, and Sino-Vietnamese readings), paleography (bamboo and wooden slip texts), historical linguistics (cognate dictionaries and neighboring languages such as Tibetan, Mongolic, Manchu, Kam–Tai, and Hmong), toponymy, and more. It also carries useful tools such as an IPA input method and statistics.
