 		<meta property="se:production-notes">Because Russian-suffix plural forms of words in M-W like muzhiki (plural of muzhik) appear, both the singular and plural forms are marked up as Russian for consistency. Two notable editorial changes I made: “passage” in chapter 30 was uppercased to “Passage” (I believe it is referring to a specific shopping street in Kyiv) and “anquettes” (not a word in any language as far as I could tell) in chapter 3 was changed to “enquetes” (a French word that is used elsewhere in the book). Chapter 40 comes from the separately-published “anti-climax,” which was the last chapter of the original manuscript. Subjects sourced from WorldCat.</meta>
