A feature like this wold be very welcome. At the moment on Pressbooks.com, for example, it appear you need to go to the directory to find things. This isn't as open as the content itself. I recommend looking at the FAIR principles (https://www.go-fair.org/fair-principles/). Whilst they are designed to make scientific data reusable, this can also apply to open books. Whilst it is OK to be able to download the book, see the licence etc, it is not good enough unless you address Finable properly. ensuring this is standardised also makes it Interoperable and would allow services globally to direct potential users to content.
Feature Description
We produce metadata/microdata for all books using schema.org taxonomy and expose this information for all public books via REST api. Sample book endpoint at https://integrations.pressbooks.network/wp-json/pressbooks/v2/books. Pressbooks Directory displays JSON metadata for thousands of educational books which have been collected from ~100 separate Pressbooks instances and stored in a document database (Algolia). Directory records are updated hourly (pulling in any changes to book metadata from individual networks via API).
The Open Publication Distribution System (OPDS) catalog format is a syndication format for electronic publications based on Atom and HTTP. OPDS catalogs enable electronic publications to be aggregated, discovered, and distributed more easily. It is based on the Readium Web Publication Manifest model, with a focus on aggregating publications to facilitate their distribution. OPDS 1.2 was released in November 2018, and there is currently a draft version of OPDS 2.0. The major change appears to be a shift from Atom XML formats to JSON-LD.

We are interested in producing an OPDS 2.0 feed that anyone could subscribe to to see the latest titles published in the Directory and allowing individual networks or authors to produce OPDS records for their individual books.
Other Notes
Publication in our open education/OER ecosystem is generally much more informal for most of these titles than they would be in a traditional university or commercial publishing house. Some, but not all, of our published titles also have EPUB or PDF exports available for public download.

This sample cataogue from Feedbooks: https://catalog.feedbooks.com/catalog/index.json illustrates most of the core concepts in OPDS 2.0:
Feedbooks offers a primer on OPDS 1.x, a sample catalog. There is some (10 year old) validation tools available for OPDS 1.1 at https://opds-validator.appspot.com/ + https://github.com/zetaben/opds-validator-web + https://github.com/zetaben/opds-validator
