Delta Think Provides Analysis on the Growth of the Directory of Open Access Books (DOAB) 

From a Delta Think Analysis by Dan Pollock:

This month we examine how the growth of the Directory of Open Access Books (DOAB) has developed over the last 18 months. We look at some key statistics from the Directory and examine the continuing growth in OA Books.

The DOAB now claims to have well over 60,000 titles, and continues to grow. The chart below shows how the index has grown.

The DOAB continues to see strong growth, and continues to outpace the growth in journals. Over the 5 years to 2022, its CAGR was 34%, compared with 22% for OA journal articles.

Growth has previously been driven by larger organizations coming on board, plus a growing long tail of publishers joining OAPEN. However, with the growth in the numbers of publishers slowing, it seems that the index is increasingly reflecting the underlying growth in the market, rather than a growth in the adoption of its infrastructure.

Books show less consolidation than journals. The top 10 OA book publishers cover around 45% of book output, while the top 10 OA journal publishers account for around two thirds of OA journal output. This may partly reflect the greater maturity of the journals market. However, it’s likely to be a systemic reflection of how books scale differently.
