This paper argues against the assertion that several of Kant’s writings were published in the form of pirate editions. It seeks to establish that most of the the editions in question (printed between 1769 and 1803) were lawfully printed. Presumably, these editions were to be sold exclusively at book fairs in Frankfurt and Leipzig; both locations are printed on their title pages, although no information on the publisher is provided. The paper also presents crucial results of detailed comparisons of all contemporary editions of Kant’s writings and delivers a short historical sketch of eighteenth-century copyright law and the philosophical debate on this topic. Finally, the importance of book fairs for trading and selling books at that time is emphasized.

为什么所谓的康德著作再版是合法版本。论发行量比较的用处和书展的历史重要性

本文反对康德的一些著作以盗版形式出版的说法。它试图确定大多数有问题的版本（1769 年至 1803 年之间印刷）都是合法印刷的。据推测，这些版本将在法兰克福和莱比锡的书展上独家销售；这两个地点都印在标题页上，但没有提供有关出版商的信息。该论文还介绍了对康德著作的所有当代版本进行详细比较的重要结果，并简要介绍了 18 世纪版权法的历史概况以及关于该主题的哲学辩论。最后强调了当时书市对于买卖图书的重要性。
