Recommendations For Crossref Reference Linking

  • Crossref Information Page - publishers will create a marketing page that links to the informational Crossref website (http://www.crossref.org), explaining Crossref. Copy for this page can be created from our marketing copy page (http://www.crossref.org/06members/48copy.html). Members may also link to Crossref's Info for Researchers page.
  • Crossref members should place a "Crossref Member" logo, which links to the Crossref Information Page or the central Crossref website, on the page where references are displayed for end users and on journal homepages. (Logos are available here.)
  • Crossref members should place a "Crossref Member" logo, which links to the Crossref Information Page or the central Crossref website, on their Response Page (the page that users arrive at when following a Crossref DOI reference link). (Logos are available here.)
  • Each publisher should either use "CrossRef" as the text of the link using Crossref DOIs, or link the actual DOI, like this http://dx.doi.org/10.1175/1520-0442(1988)001<0715:COAPSR>2.0.CO;2. Please view Crossref's DOI display guidelines.
  • Response Page - this is the page that users see when they arrive at a publisher's site after following a Crossref DOI link from another publisher's site. Members should display a Crossref Member button that links to their Crossref Information Page.

The items above are recommendations, not requirements.

Reference Link Formats

Outgoing Links

These are links that publishers add to the references in their journals using Crossref DOIs.

Options for links:

** Kaplan D. R. (1994) J. Neurobiol. 25, 1404-1417. http://dx.doi.org/10.1002/neu.480251108
Kaplan D. R. (1994) J. Neurobiol. 25, 1404-1417. [Crossref] [Medline]
Kaplan D. R. (1994) J. Neurobiol. 25, 1404-1417. [Crossref] [Medline]
Kaplan D. R. (1994) J. Neurobiol. 25, 1404-1417. [Original Article] [Medline]

**Recommended Format

Text link following the reference - Crossref is preferred because this is short and simple. We discourage using "Crossref Full Text" or "Crossref Article" as they imply the user will get the full text when they may not depending on their access rights.

Intermediate Link Page - publishers can have a link that says [Links] that will take the user to an intermediate page where all links that are available are displayed.

Crossref Name


Crossref should always be written with an uppercase "C" and "R" and as one word. Crossref® and Crossref.org® are registered trademarks, and the Crossref logo is a trademark of PILA (Publishers International Linking Association).

Recommendations For Crossref Cited-by Linking (formerly known as "Forward Linking")

  • Crossref members who participate in Crossref Cited-by Linking may display the "Crossref Cited-by" logo on the page where Crossref Cited-by links are displayed for end users and on pages that describe Cited-by Linking. (Logos are available here.)
Publishers who participated in Crossref Cited-by Linking may use the following text to describe the service to their users:

"Crossref Cited-by Links display scholarly content from participating publishers and societies that cites this article.These links are enabled by Crossref DOIs, the same persistent links that connect references in this publication to content published elsewhere."

  • Each publisher should display "Crossref Cited-by Links" as the text of the link that takes end users to the page where Crossref Cited-by Links appear.
  • All former references to "Forward Linking" from Crossref should be replaced with "Crossref Cited-by Linking."

Crossref Cited-by Linking Name

To differentiate these links from links provided through other services, the terms "Crossref Cited-by Linking" and "Crossref Cited-by Links" should be used. The capitalization and punctuation is as follows: Crossref should always be written with an uppercase "C" and "R" and as one word. "Cited-by Linking" should always be written as shown here with an uppercase "C", lowercase "b", uppercase “L”, and a hyphen. “Cited-by Linking” should be written as two words.

These are recommendations, and not requirements.

Recommendations for Similarity Check Plagiarism Screening

Similarity Check plagiarism screening participants should publicly identify their membership in Similarity Check through the use of Similarity Check Depositor and Similarity Check Deposited logos. 

  1. Each publisher should create a Similarity Check Information page - a web page that explains Similarity Check and links to the Similarity Check web page (http://www.crossref.org/similaritycheck.html). Sample copy for this page can be found below.
  2. Similarity Check participants should place a "Similarity Check Depositor" logo on the home page of publications that have been deposited in the Similarity Check database. The Similarity Check Depositor logo should link to the Similarity Check Information page described in (1). We would also encourage you to place Similarity Check and iThenticate logos and information in your Instructions for Authors and, if possible, at the point of manuscript submission to inform authors about plagiarism screening and provide them with the opportunity to pre-screen their manuscripts using iThenticate for Researchers.
  3. Similarity Check participants are encouraged to include the Similarity Check Depositor logo on their printed journals.
  4. Each content item (i.e. journal article or book chapter) that has been deposited in Similarity Check may also carry the"Similarity Check Deposited" logo. This logo should link to the information page described in (1) above.


Sample Copy for Similarity Check participants to display on their Similarity Check Information Page

Similarity Check is a multi-publisher initiative to screen published and submitted content for originality.  <This publisher> uses the iThenticate software to detect instances of overlapping and similar text in submitted manuscripts. Wherever you see the “Similarity Check Deposited” or “Similarity Check Depositor” logos, you can be reassured that the publisher whose content you are reading is committed to actively combating plagiarism and publishing original research. View <publisher name>’s plagiarism policy here. To find out more about Similarity Check visit http://www.crossref.org/similaritycheck.html

The items above are recommendations, not requirements.
