原子力機構(JAEA)図書館では会議録や技術レポートを重視して収集している。これらはCD-ROMやUSB等の記録媒体を用いて電子的に刊行されることが増えているが、紙媒体と比較して電子情報の記録媒体の保管可能な年限は短い。たとえばJAEA図書館では1990年代に発行された図書と技術レポートを所蔵しているが、そのうち再生可能なソフトウェアがなく、利用できなくなっているものもあり、長期保存や利用環境の維持が課題である。対策としては資料と再生機器のメンテナンス、エミュレーションやマイグレーションが望ましいが、十分にできているとは言い難い。電子情報の長期保存と利用についてJAEA図書館の現状を報告するとともに、公刊された電子媒体情報がGreyになりつつある点について問題提起をしたい。

JAEA Library focuses on collecting conference proceedings and technical reports which are very important and referred materials for our users in the field of nuclear science and technology. There are an increasing number of cases that they are published in electronic media such as CD-ROM and flash memories. There are problems as to manage such electronic media in a library. Largest problems for electronic media would be the long-term preservation and permanent access. Lifetime of electronic media are much shorter compared with paper and/or microfilm. In this regard, the JAEA library is struggling to preserve electronic media including related PCs and software for a long-term. One of the effective countermeasure should be preserving PCs and software to browse, emulation and migration to another media. However, our countermeasure is not good enough for users and preservation. The authors would like to present JAEA Library's current activities on long term preservation and use of electronic media, and it comes to the conclusion the fact that even published electronic media are becoming grey literature in certain environment.
