In this paper, through my experience of supporting the use of GLAM data in digital archives, I discussed the necessity and the methods of preserving and utilizing GLAM data by integrating geospatial information and GLAM data from the standpoint of geospatial information. In the future, GLAM data, including Japan Search, will require the development and refinement of location information metadata by GLAM institutions, the field of geographic information science, and citizen participation, such as the transfer of geocoding methods from addresses and the development of a WebGIS mechanism that allows location information metadata assignment. On the side of geographic information science, it is necessary to organize and provide bone digital geospatial information in terms of digital archiving.
