Submitted Works

This is an umbrella term for all items previously submitted to any of the repositories that an account has been set up with. The following repositories are potentially available:

  • Private organizational repository
  • Private group repository (e.g. country, consortium, or a specifically requested group)

By default, all accounts are set up with their own private institutional repository.

As a Crossref customer, any content you submit to Crossref Similarity Check will not be indexed into a publicly searchable repository.
