Any author will ask questions such as the ones above, and academic authors are no exception. In one sense, we have better answers than were possible just 20 years ago. Although thousands of copies of print books are sold per year, in those days there was little evidence coming back to the publisher that those books were actually read. In fact, one joke among publishers was that encyclopedias and bibles had one thing in common: they were more bought than read. A typical publisher would receive just a handful of comments from readers each year. As publishers, we knew the books were sold; but we didn’t know if they had ever been read. So if an author had asked us if anyone read their book, we couldn’t say.
