Comprehensive Archive (IJCA) [mainly in Ja]
Iwasaki Junichi Comprehensive Archive (IJCA) is a huge archive IJAI owns. We have accumulated materials and knowledge comparable to one university faculty or one small university, centering on the copyrighted works that Iwasaki Junichi and his related members or parties created, and academic materials and classical books that they privately own. The IJDC codes of IJCA are all from [0 sector] to [9 sector].
