CrossRef is an association of scholarly publishers that develops shared infrastructure to support more effective scholarly communications. Our citation-linking network today covers over 65 million journal articles and other content items (books chapters, data, theses, technical reports) from thousands of scholarly and professional publishers around the globe.

 


WHAT IS CROSSCHECK?
CrossCheck powered by iThenticate is an initiative started by CrossRef to help its members actively engage in efforts to prevent scholarly and professional plagiarism. Although there are several plagiarism screening tools already available, they are not well-suited to filtering academic content simply because they haven't had access to the relevant full-text literature to screen against. CrossCheck changes this by creating and continuously growing a database of current and archival scholarly literature.

 


Cited-by Linking
CrossRef Cited-by Linking (formerly Forward Linking) is a service that allows you to discover how your publications are being cited and to incorporate that information into your online publication platform. Participation in CrossRef Cited-by Linking is entirely optional and there is no charge for it, but in order to participate, there is an important quid-pro-quo: in order to discover what publications cite your content, you must in turn submit metadata listing the works that your publications cite.

 


What is DOI?
A digital object identifier (DOI) is a character string (a "digital identifier") used to uniquely identify an object such as an electronic document. Metadata about the object is stored in association with the DOI name and this metadata may include a location, such as a URL, where the object can be found. The DOI for a document remains fixed over the lifetime of the document, whereas its location and other metadata may change. Referring to an online document by its DOI provides more stable linking than simply referring to it by its URL, because if its URL changes, the publisher need only update the metadata for the DOI to link to the new URL.
