1992年,哈佛大学启动了一个庞大的计划,这一计划是要在1998年以前将500万张卡片式书目记录转换成机读目录形式。或许是因为有如此庞大规模的计划的特点,它的规划工作开始于好几年以前。这篇文章将介绍这一从开始第一条记录到全部完成需费时6年的计划启动前的规划过程。它要说明进行回溯转录对于图书馆来说是何等的重要,对于学术又为什么具有十分重要的意义。 In 1992, Harvard University launched a massive program to convert 5 million card-based bibliographic records into machine-readable catalogs by 1998. Perhaps because of the characteristics of such a large-scale program, its planning began several years ago. This article will introduce the planning process prior to the start of the six-year plan from the first record to the completion. It shows how important back-transcription is to the library, and why academic is so important.
