About the book: 1931 / Book "Zavadsky V.V. (V. Korsak). The whites. 1931 edition.” The first version of this DjVu book (there are about 600 books in total) was created on the website http://rusviv.com and is sold there for money, although all works of that era have long been out of copyright. To ensure that the resulting book text (and the author did a lot of work) could not be stolen and indexed by search engines, the author first recognized a pre-revolutionary book, created a text file, and then generated a DjVu, but only with an image layer without a text layer.
