Digital Object Identifiers (DOIs) uniquely identify a paper or part of a paper and enable reliable and persistent links to be created between papers. A DOI can be "resolved" to the paper's location on a web server using the DOI Resolver. EJMS uses DOIs to identify all accepted papers. When the paper is first accepted it is assigned a DOI and it is published (with the permission of the author) on the web as a Just-Published Paper (JPP). The DOI can be used to cite the paper, since we will ensure that it always points to the latest version of the paper on the web. When a JPP is published, the DOI will point to the paper in its temporary form and location. Once it has been finally published in its copy-edited and typeset form, the DOI record will be updated with the new location.

A DOI is made up of a publisher-specific prefix (IM Publications' is 10.1255/) and a suffix devised by the Publisher to identify the object uniquely. For EJMS this will typically be ejms., followed by a unique internal number.

The DOI will always point to the paper's latest location, so can be used as a reliable citation.

IM Publications is a member of CrossRef, an organisation set up by publishers to handle the depositing of DOI data, to enable DOIs to be looked up by member organisations to facilitate enhanced reference linking between electronic journals and to provide the facility to resolve a DOI. This can be done using the DOI Resolver or by appending the DOI to the URL string "http://dx.doi.org/".
