NSP Membership in Crossref

We hereby announce that NSP has already been a member of Crossref and have the honor to offer the related services to all esteemed researchers and authors as follows: 

DOI Registration

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.


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.

Similarity check

A service provided by Crossref and powered by iThenticate—Similarity Check provides editors with a user-friendly tool to help detect plagiarism.

Reference Linking

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.
