La Spanish Journal of Public Opinion (1965-1977) was the predecessor of the Spanish Journal of Sociological Research (SJSR). As indicated in number 0 of April 1965, its purpose was to disseminate the scientific aspects related to the study of public opinion and contribute to the enrichment of the political life of our country.
The SJPO published many articles by researchers and scholars of Social Sciences, some of which, over the years, became prestigious Spanish and Spanish-language academics, sociologists and political scientists.
It is a reference publication for any student of Spanish and international society and politics of those years and now, since November 2020, has became free-to-air on line.
