The pure self-archiving seems to be less preferred than librarian-mediated deposit [27].
Even if metadata templates are provided
and librarians assist authors to deposit their work,
the difficulty in using IR may still remain from the authors’ point of view.
As a result, it is claimed that IR contributions simply represent extra workloads.
Then academics tend not to participate in this service.
The context of IR raises questions about information professional’s role in metadata management
and metadata quality control for digital assets.
