Create Views listing back-references
You'll probably have to create a new View for each of the bundles you're using references on (Content, Taxonomy term, File, Comment etc).
The key is to be aware of your project structure, to know where all of the reference fields are. So check your "Manage fields" pages everywhere for reference fields, and note what they reference. Then create a back-reference map from that info so you know which Views you need to create.
You may end up with less Views depending on your structure, you'll need as many as there are entity types that are being referenced. Then if more than one type references it you can use Relationships to add them to the same view. This way you could have taxonomy terms type View that lists all Content and Files that are tagged with it.
Which Relationships and (Contextual) filter exactly needs to be used depends on the particular structure you have. You can use an Exposed filter instead of a Contextual if it's just a tool to check references, but if you want to display a Block on relevant (Edit) pages that would automatically show what references this (smart) then you need the Contextual.
For example, if you have articles referencing other articles through Entity reference field:
- Create View with Block display listing articles
- Add the Contextual filter for that Entity reference field:
When the filter value is NOT available
Provide default value
Content ID from URL
When the filter value IS available or a default is provided
Specify validation criteria
Hide View if the argument doesn't validate, or some other options that makes sense to you.
- Place the Block on article pages, or article edit pages, adjust
Node from URL and other Block options.
The block will show if there are any articles that reference the one you're viewing.
Other types of connections will require similar or other types of Views configuration.
