The invention of photography in the 19th century made possible a new kind of record, and collections of photographs are popular, particularly in public libraries with an interest in local history. Specialized photo libraries, such as the BBC Hulton Picture Library, are regularly used to provide illustrative material for film and television programs.
For the general use of libraries, however, microphotography has played a much more important role. Many leading newspapers and periodicals have reproduced their entire sets of back issues on roll film, which offers a considerable saving of space and makes it feasible for even a small library to house an entire set. The disadvantage of roll film is that the user must start searching the roll film from the beginning of the reel, no matter where the relevant pages may be on the reel. A considerable advance was achieved by the invention of the transparent Microcard, or microfiche. This is a piece of film cut to a specified size and

19世界发明的照相术使一种全新的记录方式成为可能，（当19世纪照相术被发明，一种全新的记录方法诞生了，）收集照片蔚然成风，特别是那些对地方志有着浓厚兴趣的公共图书馆。诸如此类像英国广播公司哈尔敦图片资料馆的专门图片馆则定期为电影和电视节目提供图片资料。
然而，缩微照相术对于图书馆的普遍利用意义重大。许多主要报刊正是通过胶片将它们的往期出版物完整再版。这样一来节省了不少空间, 使得那些相对较小的图书馆也可以将整套内容都收入其中。但用胶卷记录也存在着弊端，无论使用者所要找的页码在胶卷的什么部位，都得从头搜起。透明缩影卡片（或者叫微缩胶片）的问世带来了巨大的进步。这种卡片由胶片按照特定尺寸和形状切割而成，相当于图书馆目录卡的大小，拥有多种可用尺寸（公认使用的尺寸为5*3英寸，即8＊13厘米）。缩影卡片的先进之处在于其支持任意搜寻，即搜索者可以将任意一部分卡片上的内容演示出来。与此同时，缩影胶片储存和处理起来也更加便捷，因此被普遍应用于目录，参考书目的制作以及文本的复制。
望满意。
