Digital Object Identifiers (DOIs)

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.

IM Publications 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. This will typically be the journal's abbreviation (ejms, jnirs, jsi or nirn), followed by a dot and a unique internal number. The DOI will always point to the paper’s latest location, so can be used as a reliable citation. To cite a paper using only the DOI, you should include the authors, the title of the paper (if allowed by the reference style of the journal you are submitting to), the journal name and the DOI. An example would be:

  1. E.A. Vorontsov, T.Yu. Samgina, V.A. Gorshkov, N.B. Poljakov, I.E. Nifant'ev and A.T. Lebedev, “Matrix-assisted laser desorption/ionization-post source decay fragmentation of cystine-containing amphibian peptides with novel cysteine tags”, Eur. J. Mass Spectrom. doi: 10.1255/ejms.1110

Citation linking

As well as providing reliable and persistent links to papers, we use DOIs to provide hyperlinks from references in our papers to the cited paper on its publisher's website. This makes it simple for subscribers to jump quickly to cited material that they are interested in.


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 "".
