ABSTRACT This essay comments on the articles collected for this special issue about international expositions in France. It finds four major themes for new directions in exposition studies. First is the long literary and cultural shadow of expositions, or the shifting timescales that gave these temporary events lasting legacies. Second are the (often unintended) concrete consequences and costs for host cities of expositions understood as mega-events and mega-projects. Third is the inverse or obverse of ‘display’, those things that expositions conceal or hide. Fourth are the ways that expositions shaped and were shaped by the world beyond their gates.

环球博览会：幕后与展览馆之外

摘要本文对本期特刊中有关法国国际博览会的文章进行了评论。它找到了博览会研究新方向的四个主要主题。首先是博览会的长期文学和文化阴影，或者使这些临时事件具有持久遗产的变化的时间尺度。其次是对博览会东道城市的（通常是意料之外的）具体后果和费用，这些博览会被理解为大型活动和大型项目。第三是“展示”的反面或正面，这些东西隐藏或隐藏。第四是博览会如何塑造世界之外的世界。
