Premier Science participates in Crossmark, to maintain the content published and to alert readers to changes if, and when, they occur.

What is Crossmark?
Crossmark, from Crossref, provides a standard way for readers to locate the current version of a piece of content. Premier Science recognises the importance of the integrity and completeness of the scholarly record to researchers and librarians, and attaches the highest importance to maintaining trust in the authority of its electronic archive. By clicking the Crossmark button, readers can determine whether changes have been made after publication. It may also provide additional publication record information about the document.
The Crossmark button
Here is how the Crossmark button is displayed on either html or PDF versions of a paper.
Types of updates
If a registered item is updated, different metadata will be recorded for the update. This is only necessary for editorially significant changes—those that are likely to affect the interpretation or crediting of the work, and where a separate update notice is usually published. Minor changes are made directly to the content without notifying Crossref, including cases such as minor spelling corrections or formatting changes that don’t affect the metadata.
There are 12 defined types of update accepted in the Crossref schema:
- addendum
- clarification
- correction
- corrigendum
- erratum
- expression_of_concern
- new_edition
- new_version
- partial_retraction
- removal
- retraction
- withdrawal
