Most of the chapters of Sandy's Selection (the book) initially appeared as individual stories in Steele Rudd's Magazine in 1903-1904. However some of the stories initially appeared in The North Queensland Register (Chapter I), The Commonwealth Annual (Chapters II - VI) The Queenslander (Chapter XI) and The Bulletin (Chapters XII, XIII, portions of XV, XVII). Chapter XVIII ('Dad Takes to Politics') and Chapter XIX ('Dad in Parliament') were later used as the opening three chapters for Dad in Politics (1908). Notably, for the book, alterations were made to the order in which the stories appeared, some of the stories were divided into two chapters or even amalgamated into one chapter, some story titles were added or altered, and a number of minor changes were made to the text. So there is not always a straightforward match up between the stories as they first appeared in Steele Rudd's Magazine and the later book chapters.
Note that whilst Sandy's Selection (the book) was illustrated by a number of artists (principally Lionel Lindsay), the stories that appeared in Steele Rudd's Magazine were illustrated by E. Ashton Murphy, with the exception of the two Dad in Politics stories, which were illustrated by George Taylor.
