What is a DOI, and why should I include it in an EndNote record?

A DOI is a unique alphanumeric string assigned by a registration agency http://www.doi.org/ to identify content and provide a persistent link to its location on the Internet. Many scholarly publishers have begun assigning a DOI to journal articles and other documents. Some editors now expect authors to include DOIs in their reference lists.

EndNote X1 includes a DOI (Digital Object Identifier) field in each reference type (journal article, electronic book etc). The American Psychological Association (APA) referencing style in EndNote X1 has been updated to comply with the APA Style guide to electronic references, and the ‘Electronic article’ reference type now displays the DOI where it has been included in an EndNote record.

Records exported to EndNote from some databases will automatically include the DOI, but in other cases, you will need to edit exported records, and manually add the DOI data. Because the DOI string can be long, it is safer to copy and paste whenever possible to avoid data entry errors.
