It is important to make sure that readers and users can find and cite the final version of your article from ScienceDirect. The way to do this is to include the Digital Object Identifier (DOI) link in your posted article. A DOI is a standardized method for identifying an electronic object, and you can easily find your DOI under the title of your article. To convert a DOI to a Web address, add the following URL to the DOI: https://dx.doi.org/ followed by your DOI number. We recommend you include this information to your title page or header/footer.
