一、四分之一世纪内档案缩微照相技术的发展(1950—1975)一九六○年,在斯德哥尔摩第四次国际档案大会上,除其它一些技术问题外,有三个文件概括地说明了关于一九五○年到一九五九年档案缩微照相领域内的技术发展问题。这三个文件按地理和政治特征区分为:美国、社会主义国家和西欧。文件具有这样的特点,即作者没有局限在档案管理范围内,而是涉及了许多对档案并不适用的设备和材料。假如我们概括一下这次会议三个文件的内容,那就是:在档案工作中使用35毫米的胶卷,一般说来是被接受了,而且希望在数量上有所增长;新的复印机,主要是静电复印机的使用正在增多;除了35毫米的胶卷外,档案馆只使用散页片,70和105毫米的胶卷只是作为一种改善的可能被提到。一九六六年在华盛顿举行了一次国际档
I. The Development of Microfilming Technology in the Fourth Quarter of a Century (1950-1975) In 1960, at the Fourth International Archives Congress in Stockholm, among other technical issues, three documents provided an overview of the Problems of technological development in the field of microfilm archives between 1950 and 1959. The three documents are divided by geographical and political characteristics: the United States, the socialist countries and Western Europe. The document has the characteristics that the author is not limited to the scope of file management, but rather involves many devices and materials that do not apply to the file. If we summarize the contents of the three documents of this meeting, that is: the use of 35 mm film in the file work, generally accepted, but also hope to increase in number; new copiers, mainly static electricity The use of photocopiers is on the increase; with the exception of 35mm film, the archives only use loose sheets, and films 70 and 105mm are only mentioned as an improvement. In 1966 an international file was held in Washington
