Negah Scientific Publisher has already been a Crossref member and has constantly the honor to offer Crossref Services, including DOI, CrossMark, Crosscheck, Reference Linking, and Cited by, and so on, to authors, journals, and institutes.
A digital object identifier (DOI) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the Internet. The publisher assigns a DOI when your article is published and made available electronically.
All DOI numbers begin with a 10 and contain a prefix and a suffix separated by a slash. The prefix is a unique number of four or more digits assigned to organizations; the suffix is assigned by the publisher and was designed to be flexible with publisher identification standards.
The CrossMark button lets readers see the status of a work by displaying any corrections, retractions, or updates to that record.
CrossCheck is a service provided by Crossref and powered by iThenticate—Similarity Check provides editors with a user-friendly tool to help detect plagiarism.
Cited-by shows how work has been received by the wider community; displaying the number of times it has been cited, and linking to the citing content.
Reference Linking enables researchers to follow a link from the reference list to other full-text documents, helping them to make connections and discover new things.
