Bowker: 727,000 US Self-Published ISBNs Registered in 2015

Caution is important at the outset on this report. You may hear people saying that Bowker’s latest report shows 727,125 self-published titles in 2015. That is incorrect.

Publishing Perspectives has spoken with Bowker’s director of identifier services, Beat Barblan, who clarifies that the company’s newly released figures show that in 2015, 727,125 ISBNs were applied to self-published works. That figure includes print and digital books, combined.
