Neil Gaiman's Journal: More on free and suchlike
Remember: one in four adults read no books last year. Among those who said they had read books, the median figure — with half reading more, half fewer — was nine books for women and five for men. The figures also indicated that those with college degrees read the most, and people aged 50 and up read more than those who are younger.
Which means you need to find ways to get young readers to read books. And means that if someone likes American Gods (It’s a free download) and goes out and buys my entire backlist, that’s more books than most Americans read in a year.
