SCURL EDI Network: EDI toolkit
This toolkit from the SCURL EDI Network aims to support member libraries in embedding good practice consistently across services. It is comprehensive and useful and comes at the topic from several angles - that of evaluating EDI in the workplace and recruitment, but also from policy and how to support students in the library.
The plan is to annually evaluate and update it, and the resource is very recent (from 2023). It covers the topic from a library point of view but has more widely applicable sections (e.g. on hiring policies).
It is a good toolkit - but specifically library (and UK)-focussed so does not fulfill the publisher's perspective need - overall a very good resource for EDI in libraries.
