As the AMA requires access to appropriate bibliographic sources to allow for further study for enduring materials activities, do we need to supply a separate bibliographic resource/resource page with each activity?

According to the AMA, there are several ways to provide learners access to enduring material resources.  One option that could be considered a best practice is to, yes, provide a separate document (e.g. bibliography or “resource center”), but this is not a requirement.  Another option is to include the reference with the relevant activity material, as providing direct access to the source materials is not a requirement.
