Citation Policy

• Authors should ensure that where material is taken from other sources (including their own published writing) the source is clearly cited and that where appropriate permission is obtained.
• Authors should not engage in excessive self-citation of their own work.
• Authors should not copy references from other publications if they have not read the cited work.
• Authors should not preferentially cite their own or their friends’, peers’, or institution’s publications.
• Authors should not cite advertisements or advertorial material.

In accordance with COPE guidelines, we expect that “original wording taken directly from publications by other researchers should appear in quotation marks with the appropriate citations.” This condition also applies to an author’s own work. COPE have produced a discussion document on citation manipulation with recommendations for best practice.
