Publishing statistics

Stuff has an interesting story on self-publishing and how e-books and Amazon make it easier.  I’m in favor of anything that produces more good books, but I would like to give two warning notes, one statistical and from my experience, and one non-statistical and from other people’s experience.

The statistical warning note is that most books on Amazon don’t sell much, if at all.  I have a book, a graduate text in a minor area of statistics, for which Amazon gives me sales data.  This book sells 2-4 copies a week through all North American bookstores (and so less than that just through Amazon). Even so, it has never been out of the top 10% of Amazon’s sales rank, it usually is at about the 95th percentile, and sometimes makes it into the top 1%.   Nearly all books on Amazon sell less than this.

The non-statistical warning note is that the self-publishing industry is historically noted for having a lot of scams.  A bit of Google due diligence is useful before you spend money on things.
