Benefits of using DOI

• Metadata repository – stores your data

• Make your contents discoverable – the more metadata you deposit with your article, the more discoverable it will be

• If the URLs or services change over time, e.g., the resource moves, this same DOI will continue to resolve to the correct resources or services at their new locations

• Persistence – no broken links

We lead

Benefits of using DOI

• Readers are more likely to find and cite articles with DOIs, which helps them and the journal

• Authors also like to submit manuscripts to journals that are more discoverable because more people will read their research!
