"In the Editor's Laboratory" is one of the three most important books devoted to the purity and richness of the Russian language (the other two are: "The Word is Alive and Dead" by Nora Gal and "High Art" by Korney Chukovsky). In her book, Lydia Chukovskaya shares her experience working in the legendary editorial office of Detgiz, recalls the great contemporary writers, talks about the principles of creating and formatting the text, about editorial censorship, widespread in Soviet times. According to the author: "this book is not a textbook on editing. I do not set any educational tasks for myself, and it is unlikely that any textbook can serve to master the art to any extent. The task of the book is different: I just wanted to sort out the experience that I and my closest comrades have accumulated, collect and summarize it, introduce the reader to the circle of those thoughts, those worries and questions that I had to come across during three decades of literary work."
