Abstract
This article views a way to record, to conserve and to show "what was / what happened here" through collecting materials at redevelopment areas. I show a process as one way of archiving, as many as possible, the things which are difficult to conserve because of some practical restrictions or which are excluded or ignored.
1. Collecting the materials which tell "what was done" and "how a person felt" at the place in daily life or work.
2. Collecting the materials which display architectural environment at the place.
3. Keeping these materials together and preparing the retrieval method which gather information for a particular place. First, I manage the materials based on archival methods and describe a catalog ruled by EAD. Second, I edit PI gazetteer and use it as a placename authority file, then the information about "here" is able to be retrieved from multiple sources. In addition, this gazetteer also plays the role "Conservation placename", by linking placename which cannot be specified by single material with another material.
Both catalog and gazetteer comply with international standards, so this way is applicable to other cases.
