All parties involved in research and publication need to discuss and agree upon the following:
The University's Research Ethics and Integrity team has developed an Authorship Policy and an associated set of procedures and guidelines.
Download the Authorship agreement template, located under 'Resources' on the University's Authorship site, to support discussions, plans and agreements about authorship.
If you have any concerns about the integrity of research, e.g. if you think authorship on a publication hasn't been fairly decided or that someone has stolen some of your original work, you should speak to a Research Integrity Advisor (RIA). RIAs are able to provide advice to any member of the University community who has concerns.

Miguel helps to define self-plagiarism within science and scholarship and review its common forms - duplicate publication, augmented publication (when a dataset is republished with additional observations), salami publication (creating two or more publications from the same study), and text recycling (re-using substantial parts of your own previously published publications). He discusses the reader-writer contract and some scenarios of re-use in books (e.g., new editions, re-using portions of chapters from one book to another, from journal articles to book), , conference presentations (e.g., presented at more than one conference, conference presentation to journal article) and doctoral dissertations and theses (e.g., dissertation/thesis to publication, publications to dissertation). He explains why authors should be concerned about re-using previously published work.
