IRIS
IRIS offers public access to materials, data, and analysis tools for research on language learning, multilingualism, and language use.

About IRIS
IRIS is a public collection of instruments, materials, stimuli, data, and data coding and analysis tools for language research. It covers first, second, and additional language learning, signed language learning, multilingualism, language education, language use, and language processing, and also holds postprints of journal articles and book chapters.
Materials are freely searchable and downloadable, and users can upload contributions that meet IRIS eligibility criteria. Search supports fields such as author, journal, research area, participant type, feature being learned, and language being learned; filters can narrow results, and multiple space-separated terms are treated as OR searches.
