1926年至1932年完成出版的李季著《马克思传》，作为中国首部中文长篇原创马克思传记，在中国马克思主义出版传播史上具有划时代意义。文章以该著作为研究对象，在研读馆藏1929年、1932年、1933年、1949年四种版本李季著《马克思传》文本的基础上，运用历史考据法，考订了从三个出版机构共同完成出版到一个出版机构独立出版的发展过程，评定了“冶马克思生平、著作、学说于一炉”“没有恩格斯，决没有马克思主义”的核心要旨，挖掘了“汇前人所作，正其讹舛”“塑造了‘战士’和‘学者’相统一的马克思形象”“为中国出版界放一异彩”的价值意义，弥补了该著作既有研究成果的不足。

 Li Ji's “Biography of Marx”, which was published from 1926 to 1932, is the first original Chinese long biography of Marx in China, which is of epoch-making significance in the history of Marxist publishing and communication in China. This paper takes this book as the research object. On the basis of studying the four versions of Li Ji's “Biography of Marx” in 1929, 1932, 1933 and 1949, using the method of historical textual research, this paper examines the publishing process from the joint publication of three publishing institutions to the independent publication of one publishing institution, and evaluates that "Marx's life, works and theories are in one furnace" and "Without Engels, there is no Marx".This paper explores the value of "summarizing what predecessors have done, which is correct", "shaping the image of Marx with the unity of'warrior' and 'scholar',and"shining for the publishing industry in China",which makes up for the obvious shortcomings of this book.
