Template:Citation Style documentation/id2

These identifiers create links and are designed to accept a single value. Using multiple values or other text will break the link and/or invalidate the identifier.

• <span id="csdoc_arxiv" />arxiv: arXiv identifier, e.g., "arxiv=hep-th/9205027".
• <span id="csdoc_asin" />asin: Amazon Standard Identification Number.
  • <span id="csdoc_asin-tld" />asin-tld: ASIN top-level domain for Amazon sites other than the US; valid values: co.jp, co.uk, ca, cn, fr, de, it, es
• <span id="csdoc_bibcode" />bibcode: Bibcode; used by a number of astronomical data systems; example: 1924MNRAS..84..308E.
• <span id="csdoc_doi" />doi: Digital object identifier; example: 10.1038/news070508-7; checked to ensure it begins with <syntaxhighlight lang="text" class="" id="" style="" inline="1">10.</syntaxhighlight>.
  • <span id="csdoc_doi_brokendate" />doi_brokendate: Date the DOI is broken; use the same format as other dates in the article.
• <span id="csdoc_isbn" />isbn: International Standard Book Number such as 978-0812695939; see Wikipedia:ISBN and ISBN. Dashes in the ISBN are optional, but preferred.

For sources with the older 9 digit SBN system, prefix the number with a zero; thus SBN 812695-93-3 should be entered as |isbn=0-812695-93-3. Checked for length, invalid characters and proper check digit.
