书刊文献具有循环利用的特性。充分发挥文献循环利用的关键是文献存取系统最佳化问题。“存”,涉及书刊文献的科学收集、处理、加工、贮存、管理等一系列问题,但核心是“贮存”;“取”,涉及用户的借阅、检索,咨询、复制以及宣传、报导等一系列问题,但核心是“获取”。存取策略,涉及两个基本概念——空间与时间。空间指空间分布,即文献存取点、面要分布合理,时间,指提高存取速率,节省时间。存取策略理论的任务,就是建立最佳化的存取系统和提高文献的存取速率。从长远看,我们必须
Books and literature have the characteristics of recycling. The key to give full play to the recycling of documents is the optimization of document access system. The “deposit” involves a series of questions such as scientific collection, processing, processing, storage and management of books and periodicals, but the core is “storage”; “taking” involves borrowing, searching, consulting, copying, propaganda and reporting of users Series of questions, but the core is “getting”. Access strategies involve two basic concepts - space and time. Space refers to the spatial distribution, that is, document access points, surface distribution to be reasonable, time, means to increase access speed and save time. The task of access policy theory is to establish an optimized access system and increase the access rate of documents. In the long run, we must
