Digital false information is a global problem and the European Union (EU) has taken profound actions to counter it. However, from an academic perspective the United States has attracted particular attention. This article aims at mapping the current state of academic inquiry into false information at scale in the EU across fields. Systematic filtering of academic contributions resulted in the identification of 93 papers. We found that Italy is the most frequently studied country, and the country of affiliation for most contributing authors. The fields that are best represented are computer science and information studies, followed by social science, communication, and media studies. Based on the review, we call for (1) a greater focus on cross-platform studies; (2) resampling of similar events, such as elections, to detect reoccurring patterns; and (3) longitudinal studies across events to detect similarities, for instance, in who spreads misinformation.

数字虚假信息是一个全球性问题，欧盟 (EU) 已采取深刻行动加以应对。然而，从学术角度来看，美国受到了特别的关注。本文旨在将当前的学术调查状态映射到欧盟跨领域的大规模虚假信息。对学术贡献的系统过滤导致识别出 93 篇论文。我们发现意大利是研究频率最高的国家，也是大多数投稿作者的所属国家。最具代表性的领域是计算机科学和信息研究，其次是社会科学、传播和媒体研究。根据审查，我们呼吁 (1) 更加关注跨平台研究；(2) 对类似事件（例如选举）进行重新采样，以检测重复发生的模式；
