The initiative began officially between 1988 and 1989 with the intention to involve the eventual microfilming of over 3 million endangered volumes. == Purpose == In the beginning half of the 20th century it became apparent that the use of acidic wood-pulp paper, common since the 1850s, was causing paper materials to slowly burn. This has been referred to as the slow fire. A statement submitted to the House of Representatives estimated that there were 80 million brittle books in North American libraries, 12 million of which were unique titles. As mass deacidification efforts proved costly and inconsistent, librarians and archivists began looking for more practical ways to preserve the intellectual content of the decaying material. Microfilm, one of the most stable and durable mediums around at the time, was decided to be the most reasonable alternative. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brittle Books Program」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
