- OA titles can generate significant print revenue. While there may be some tradeoff between OA editions and print sales, publishers can produce print sales revenue from their OA lists. Publishers may wish to take such revenue into account in considering business models for OA publication today.
- OA titles can generate meaningful digital revenue. When made available through consumer channels such as Kindle, ebooks that are available openly on other platforms can in parallel generate meaningful consumer sales. Publishers may benefit from giving focused consideration specific to OA monographs to their pricing and windowing tactics for such channels.
- Outliers are essential. A small number of OA titles sell particularly well, just as is historically the case in traditional monograph sales models. Publishers bearing this in mind will be thinking in terms of the sustainability and growth of their lists overall rather than each title individually.
- Titles with both hard and soft cover formats generate the most revenue. This may be the result of format choices publishers based on market forecasting, so from our data we cannot be sure that there is a causal relationship. Still, publishers may wish to give additional attention to their format strategy for OA books.
- Sales vary widely by field. History, arts, and humanities saw lower unit sales while social sciences saw higher unit sales and STEM fields saw the greatest. Publishers may need to pursue different sustainability models for OA books based on their field.
- An opportunity to increase print sales? There is currently significant friction for users in navigating from digital to print editions. Publishers and digital distribution platforms should work together to create a more seamless reader experience from digital discoverability of and engagement with the OA version to potential print sales.
