In the Ring With James J. Jeffries is Adam Pollack's 4th book in his heavyweight champion series. It describes in meticulous detail Jeffries' bouts from the 1890s up to 1905 (including round by round accounts as well as pre- and post-fight analysis), his opponents, and his training regimen. It discusses the time's heavyweight scene, including contenders, pre-fight hype and negotiations, political and legal obstacles, and the color line. Chapters also include descriptions and analysis of Corbett-Sharkey II, Fitzsimmons-Ruhlin, Fitz-Sharkey II, and Corbett-McCoy, as well as controversies surrounding several bouts. The book is based on next day local newspaper accounts, comparing and contrasting their descriptions and analysis in order to provide an authentic view of how heavyweight boxing was perceived at the time. The use of local primary sources gives readers a rare opportunity to relive Jeffries' career as if they were reading about it at the time he was fighting. The book also includes Jeffries' career record, over 100 photos, 924 footnotes, and an index.
