The good people at [COPIM](https://www.copim.ac.uk), in their [formal announcement of the Open Book Collective](https://hms.mediastudies.press/pub/willems-unearthing-bundles):

> OBC will act as a collector of revenues accrued for new membership packages from institutions – primarily academic libraries – with this revenue then passed on to OA book publishers and infrastructure providers. A portion of the revenue will be retained to cover the platform’s administrative overhead costs.

The Open Book Collective, when it's launched in the spring, will help solve the APC/BPC author-exclusion problem, by directly linking funders to publishers (and infrastructure stewards). I see the [OBC](https://hms.mediastudies.press/pub/willems-unearthing-bundles) as the book counterpart to the [journal-centric OACIP](https://www.lyrasis.org/content/Pages/oacip.aspx) from LYRASIS. They are—in practice, in OACIP's case, and in active development, now, for OBC—the two main examples of the [mission-aligned funding exchange](https://commonplace.knowledgefutures.org/pub/erpw9udj/).
