Excluding search repositories
You are able to exclude entire repositories from appearing in a Similarity Report. The repositories you have available to you are determined by the administrator for your organization.
Changing your settings will only change the setting for future uploads. If required, previously uploaded documents will need to be individually adjusted.
- Select Settings from the sidebar.
- Using the checkboxes, choose the repositories that you'd like your submitted documents to not match against.

Crossref & Crossref Posted Content
The Crossref repository is a collection of published scholarly works and the Crossref Posted Content collection of scholarly works that have been submitted but not yet published. Both available to search submissions against through our exclusive partnership with Crossref.
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 search-able repository.
Changing default repository settings will only change the setting for all future uploads. If required, previously uploaded documents will need to be individually adjusted.
Changes should automatically apply, but select the Done button to confirm and close the side-bar.
