The essential reading includes papers suggested by the authors for course delegates to read before they begin working through an eTutorial. They are not compulsory.
Throughout the remainder of the eTutorial where the content is referenced, the references will be listed at the bottom of the page. These papers may not be available as full-text and are for further information only, unless otherwise specified.
If we have provided an external link to the abstract of an article, you might be able to access the full-text version using a different institution’s login (for example, your Athens login). Alternatively you could consider purchasing the article.
