This "Geological Literature Search" is available, but it is data until the end of March 2020.
The new database is under construction.
These databases are a bibliographic database on earth sciences, compiled by the Library of the Geological Survey of Japan (GSJ), AIST.
This database is a database that integrates "GEOLIS+" and "G-MAPI".
You can retrieve by "Google Maps(TM)".
AIST does not express any official opinion on the contents of Google Maps(TM), which are used as a base map for this database.
