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.


 * arxiv: arXiv identifier; for example:
 * asin: Amazon Standard Identification Number
 * asin-tld: ASIN top-level domain for Amazon sites other than the US; valid values:,  ,  ,  ,  ,  ,  ,
 * bibcode: Bibcode; used by a number of astronomical data systems; for example:
 * doi: Digital object identifier; for example: . It is checked to ensure it begins with (10.).
 * doi_brokendate: Date the DOI is broken; use the same format as other dates in the article.
 * isbn: International Standard Book Number; for example: . (See: ISBN and ISBN). Dashes in the ISBN are optional, but preferred. Use the ISBN actually printed on or in the book. Use the 13-digit ISBN – beginning with  978 or 979 – when it is available. If only a 10 digit ISBN is printed on or in the book, use it. ISBNs can be found on the page with the publisher's information – usually the back to the title page – or beneath the barcode as a number beginning with 978 or 979 (barcodes beginning with any other numbers are not ISBNs). For sources with the older 9 digit SBN system, prefix the number with a zero; thus, SBN 902888-45-5 should be entered as 0-902888-45-5. Do not convert a 10 digit ISBN to 13 digit by just adding the 978 prefix; the last digit is a calculated check digit and just making changes to the numbers will make the ISBN invalid. This parameter should hold only the ISBN without any additional characters. It is checked for length, invalid characters – anything other than [0123456789 -] with "X" permitted as the last character in a 10 digit ISBN – and the proper check digit. Alias: ISBN
 * issn: International Standard Serial Number; eight characters may be split into two groups of four using a hyphen, but not an en dash or a space.
 * jfm: Jahrbuch über die Fortschritte der Mathematik
 * jstor: JSTOR abstract; for example: " " will generate JSTOR 3793107.
 * lccn: Library of Congress Control Number. A certain amount of reformatting may be necessary, such as the use of zero instead of a hyphen; for example, if the book shows "Library of Congress Catalog Card Number 89-61500", this would be entered as 89061500
