In the new courses and catalog site only published courses are shown. This makes it impossible to access wikis or blogs etc. that have been published as a standalone resource without a course context.
To address this problem, the course and catalog site should list all resource types when they are published. As published are considered resources with are set to members-only, visible to authors, visible to all users or visible to all users and guests.
Resources which are visible only to owners (not published) are only displayed in the authoring environment.
