Article numbers or IDs
Adding other identifiers
Journal articles and other scholarly works often have an ID such as an article number, eLocator, or e-location ID instead of a page number. In these cases, do not use the <first_page> tag to capture the ID - instead, use the <item_number> tag with the item_number_type attribute value set to article_number.
Example article number or ID
<publication_date media_type="online">
<month>5</month>
<day>10</day>
<year>2017</year>
</publication_date>
<publisher_item>
<item_number item_number_type="article_number">3D9324F1-16B1-11D7- 8645000102C</item_number>
</publisher_item>
<crossmark>
Internal and other identifiers
You can include identifiers that are not explicitly defined in our deposit schema section within the optional <publisher_item> section. <publisher_item> is also used to capture article or e-location IDs. This option should only be used for identifiers that identify the item being registered. Use relationships to capture identifiers for related items.
Examples of identifier types include:
- PII
- SICI
- DOI
- DAI
- Z39.23
- ISO-std-ref
- std-designation
- report-number
- other
Example of an identifier
<publisher_item>
<identifier id_type="**pii**">s00022098195001808</identifier>
</publisher_item>
