Lithuanian Data Archive for Social Sciences and Humanities (LiDA) is a virtual digital infrastructure for SSH data and research resources acquisition, long-term preservation and dissemination. It provides access to more than 600 data and research resources. All the data and research resources are documented in both Lithuanian and English according to international standards. Access to the resources is provided via this Dataverse repository (not all the resources are available, as in 2020-2024 a migration project from the old infrastructure is being implemented). LiDA curates different types of resources and they are published into catalogues according to the type: Survey Data, Aggregated Data (including Historical Statistics), Encoded Data (including News Media Studies), and Textual Data. Also, LiDA holds collections of social sciences and humanities data deposited by Lithuanian science and higher education institutions and Lithuanian state institutions (Data of Other Institutions). LiDA is hosted by the Centre for Data Analysis and Archiving (DAtA) of Kaunas University of Technology (data.ktu.edu).
