In-Depth Research Guide
The Indo-European Etymological Dictionaries Online (IEDO) reconstructs the lexicon for the most important languages and language branches of Indo-European. It is a rich reference source for historical and general linguists. Dictionaries can be cross-searched, with an advance search for each individual dictionary enabling the user to perform more complex research queries. Each entry is accompanied by grammatical info, meaning(s), etymological commentary, reconstructions, cognates and often extensive bibliographical information. New content will be added on an annual basis.
Linguistic Bibliography Online
The Linguistic Bibliography Online covers all disciplines of theoretical linguistics, both general and language specific, from all geographical areas, including less-known and extinct languages, with particular attention to the many endangered languages of the world. The online edition contains all entries of the printed volumes as of 1993 and new records are added on a monthly basis.
