The Indo-European Etymological Dictionaries Online (IEDO) reconstruct the lexicons of the most important languages and language branches of Indo-European. As of 2023, IEDO is available for libraries in two different formats.
IEDO – Consolidated Database is a unified online resource containing most of the individual dictionaries, as well as some additional dictionaries that are not offered individually.
There are three search options: single language, all languages, or a subset of two or more languages. In addition to simple searches, literal (whole-word) searches are also possible. Entries are accompanied by grammatical information, meaning(s), etymological commentary, reconstructions, cognates, and bibliographical information. From time to time additional dictionaries will be made available for purchase. Updates to existing dictionaries, consisting of additional and revised entries, are provided as a free service to subscribers.
NEW features as of 2023:
Online dictionaries are available individually for the first time
Literal (whole-word) search box added
Multiple searches on a subset of languages made easy via a cluster page
Two new online resources will be added to the consolidated database in September 2023: A Digital Concordance of the R̥gveda by Alexander Lubotsky, and The R̥gveda: The complete text with Geldner's and Griffith’s translations
Updates to existing dictionaries provided as a free service to subscribers
