DOIs & ARKs explained¶
Every published item in the AU-IR carries two permanent identifiers. They make sure a link to an item keeps working for the long term — even if the website changes.
What they are¶
- A DOI (Digital Object Identifier) — looks like
https://doi.org/10.67178/.... This is the primary, official identifier. It's what you cite, and what Google Scholar, Crossref, and other indexes use. - An ARK (Archival Resource Key) — looks like
ark:/53360/.... This is a backup permanent link, hosted by Amoud, that always resolves to the item.
Which one do I cite?
Cite the DOI. The ARK is a durable fallback; the DOI is the one the academic world recognises.
Why permanent identifiers matter¶
Ordinary web links break when pages move. A DOI or ARK is a promise: it will always redirect to the item's current page. That's why journals and reference lists use them instead of plain links.
Where to find them¶
Both identifiers appear on every item page, near the title and in the citation panel.
