This article examines how the digital is politicizing medium within historical studies. Through a critical evaluation of Mass Observation Online (MOO: the online portal for the Mass Observation Archive), the paper traces how OCR (Optical Character Recognition) has established a new hierarchy in a key archive of British social memory, centred around the typewriter, whose products are much easier to digitize. It shows how a new economy of representation has been created based not on what Observers wrote, but what they wrote with. This has serious historiographical consequences for research drawn from MOO. Typewriting during the interwar period was connected to wider historical forces, including changes in white-collar work, gender roles and cultures of representation. Privileging typewritten material, therefore, is changing how we understand MO materials: from the constitution of the national panel, to the identity of observers, the form and content of materials, and the nature of life-writing. This distortion is not limited to MOO, but the digital has made medium a key site around which primary source materials, archival collections and digital interfaces are being structured. As historical collections are increasingly accessed through digital interfaces, it is argued that increased attention must be paid by historians and archivists to the historiographical dimensions of media and its impact on digital historical collections.

在线打字大规模观察：数字档案上的媒体烙印

本文探讨了历史研究中数字化如何使媒体政治化。通过对“网上质量观察”（MOO：Mass Inspection Archive的在线门户）进行的严格评估，该论文追踪了OCR（光学字符识别）如何在以打字机为中心的英国社会记忆的主要归档中建立了新的层次结构，其产品更容易数字化。它显示了如何基于观察者的书写而不是观察者的书写来创建一种新的表示经济。这对从MOO进行的研究产生了严重的史学后果。两次战争之间的打字与更广泛的历史力量有关，包括白领工作的变化，性别角色和代表文化。因此，特权打字材料 改变了我们对MO材料的理解：从国家专家组的组成，到观察者的身份，材料的形式和内容，以及生活写作的本质。这种失真不仅限于MOO，而且数字媒体已成为构建主要来源材料，档案馆藏和数字接口的关键场所。随着人们越来越多地通过数字接口访问历史收藏，人们认为历史学家和档案工作者必须更加注意媒体的历史学方面及其对数字历史收藏的影响。但是数字媒体已成为媒体构建主要来源，档案馆藏和数字界面的关键场所。随着人们越来越多地通过数字接口访问历史收藏，人们认为历史学家和档案工作者必须更加注意媒体的历史学方面及其对数字历史收藏的影响。但是数字媒体已成为媒体构建主要来源，档案馆藏和数字界面的关键场所。随着人们越来越多地通过数字接口访问历史收藏，人们认为历史学家和档案工作者必须更加注意媒体的历史学方面及其对数字历史收藏的影响。
