The paper deals with the topic of the data archiving in the social sciences. It illustrates the positive influence of archiving on the methodological standards and the innovation of a research, which is based on a knowledge gained from the previously carried out research. The study proceeds with the history of the world-wide social sciences archive infrastructure and presents the Slovak Archive of Social Data (SASD, http:// sasd.fphil.uniba.sk or http:// sasd.sav.sk). It further analyses the importance of the data archiving for the participation in the cross-national comparative surveys and points to the possibilities that archiving infrastructure offers when solving the methodological issues in a cross-country research. The conclusion outlines the further development of the Slovak Archive of Social Data - expansion of the archive and the cataloguing of existing research where it appeals to a culture of the data sharing.
