In this example, Zotero is displaying the references it can retrieve. The OpenURL referrer is responsible for the Find in a library links.

ContextObjects in Spans, commonly abbreviated COinS, is a method of embedding latent OpenURL ContextObjects in web pages. This allows client software to retrieve bibliographic metadata and to use an OpenURL resolver to find a mediated link. A principal advantage of using COinS, rather than giving a static OpenURL, is that the client can determine which resolver to use. This allows, for instance, searching for a copy of a book in one's own library.

COinS have been added to various parts of Wikipedia. They are basically just a chunk of bibliographic information stored in a way that machines can read. This has two applications:

  • The information can be converted into a full OpenURL and resolved by a local OpenURL resolver. For instance, with LibX, OpenURL referrer,[1] or a similar extension or bookmarklet installed in Firefox, a link will appear after many of the books and journal articles in a Wikipedia article's References section. If the extension is configured correctly, the user can click a link after a book to check if his organization's library has a copy. If the organization has the appropriate access, clicking the link after a journal article may bring up a copy of the article.
  • The information can be stored by bibliographic tools like Zotero.[2] The tool can download the bibliographic information from an article into a personal library for future research and retrieval.
    • Zotero also has Wikipedia export,[3] which allows references to be dragged into a Wikipedia edit box, where they will appear formatted as Wikipedia citation templates.

So far, COinS have been added to:

It adds pages to the above category.

Templates needing COinS[edit]

COinS could, and should, be added to these templates:

The COinS keys used in most Citation Style 1 templates are listed at Module talk:Citation/CS1/COinS.
