"This is the third annual sales analysis issued by Nielsen Bookscan SA, the purpose of which is to obtain an overview of the trade sector of the South African book industry over the twelve months of 2008 compared to the twelve months of 2007, in order to identify the areas of growth during this period. The sources of the growth are identified in terms of the contributions to total sales values made by frontlist publications and the top 100 bestselling titles. Analysis is provided for each of five product categories: adult fiction, adult non-fiction, children’s books, school books and academic and/or specialised publications. Distinction is made between four product segments in terms of the source and language of books: all publications, imported publications, local English language publications, and Afrikaans publications."
