"Housei Keizai Shakai Ronbun Souran" (Catalogue of Academic Papers on Law, Politics, Economics and Sociology) and its additional version edited by Keitaro Amano were published in 1927 and in 1928 respectively. They cover collection of indexes of important academic papers and articles on law, politics, economics and sociology published in academic journals and books during the period from the Meiji Restoration until Showa 2nd year, and they still remain one of main, important sources of information for surveying old documents of those days. We have been working on the construction of web-version information retrieval system on the database of the two indexes, the whole text information of which has been converted into XML style. Our system is now released on our website. In the present paper we describe how our system has been developed and how it can be used.
