Digital object identifiers or DOIs are links guaranteed to remain valid even if articles move between DOI-compliant platforms such as ScienceDirect.
Regardless of the publisher or author of an online publication, the structure of a DOI link is always the same, which makes DOIs easy to use.
DOI links have the following structure: http://dx.doi.org/doi.
An example is http:dx.doi.org/10.1016/j.iheduc.2003.11.004.
A DOI entered in a Web browser must be preceded by http://dx.doi.org/.
On ScienceDirect, the DOI appears in the top left area on each article. When Elsevier-published articles are cited, Elsevier asks that their DOIs be included. Stating the DOIs may help current or future researchers find cited articles.
