Using the American Psychological Association (APA) style for electronic reference in EndNote X1

• When citing a journal article that you accessed electronically, use the ‘Electronic article’ reference type. Enter the Digital Object Identifier (DOI) of the article in the DOI field. If the article has no DOI, use the URL field and enter either the URL of the journal's website (for subscription journals), or the full URL of the article (for articles available free on the web).
• When citing an electronic book, use the ‘Electronic book’ reference type. If the book is freely available on the web, enter the URL in the URL field. If the book is only available from a subscription database, just enter the name of the database in the Name of Database field. You will need to manually edit the entry in the reference list to italicise the title of the book, i.e. there is not a separate reference type for chapters in an electronic book.
• For an online report, use the ‘Report’ reference type and enter the URL of the report in the URL field.
• For a thesis which is available online, use the ‘Thesis’ reference type. Enter the URL in the URL field, if the thesis is freely available. If the thesis is only available via a subscription database, enter the name of the database in the Name of Database field.
• Use the ‘Web page’ reference type for other online sources. Enter the URL in the URL field. Enter data in the Last Update Date field, if available. If appropriate, enter data in the Type of Medium field, e.g. Video file, Press release, PowerPoint slides, Audio file, Abstract.

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.
