本文所要探讨的,只是档案利用在客观上的空间和时间限制,不涉及人为的空间和时间限制,如档案利用的范围限制和保密时限等。档案利用的空间限制,主要有:一、档案馆和利用者属地的距离。档案是人类社会实践活动的真实历史记录,原始性乃其本质属性,原本原稿,原声原象是其重要特征。因此,档案材料大部分都是孤本,“物以稀为贵”,档案的价值是难以计算的,它是国家的宝贵文化财富。为了确保其完整和安全,便于当前和今后长期利用,档案必须按照集中统一管理的原则,集中保存 What we want to explore in this paper is just the objective space and time constraints of file utilization. There are no man-made space and time constraints, such as the limitation of file usage and the confidentiality time limit. Archives use of space constraints, are: First, the archives and users of the distance to the ground. Archives is a true historical record of the practice of human society. Primitiveness is its essential attribute. The original manuscript and the original soundtrack are their important features. Therefore, most archival materials are lonely, “rare things are rare,” the value of the file is difficult to calculate, it is the country’s precious cultural wealth.
