tlCorpus - Concordance Software
No serious language specialist today does work without the aid of Corpus Query Software to readily and rapidly study actual language usage. tlCorpus allows you to compile a database of texts in one or more languages, and then allows you to conduct searches on the texts or compile statistics or generate wordlists.
