Classifying open access business models
This resource is an article offering a comprehensive classification system for OA models, categorising them into five core types (transactional, bundled, cooperative, sponsored, and alternative), each with distinct characteristics and implications for funding, equity, and implementation. It is extremely new, and the author is refining it on the basis of feedback (including from Copim members), and is very comprehensive and clear, and also does not use the colour coding system. Definitely a good resource to link to.
