A printed book is marked in the list of references as follows:
Author’s last name, the first letter of the author’s first name. Year of publishing. Name of the book (in italics). Edition (if more than one). Place of publishing: Publisher.
In case the book’s editor is known, but the information on the authors of the different chapters is not indicated, the reference can be made using the title of the book. The name(s) of the editor(s) is not mandatory information so it can also be left out if desired.
An electronic book, an eBook, is included in the references in the same way as a published book, however a permanent address and reference date must also be added at the end of the reference:
Author’s last name, the first letter of the author’s first name. Year of publishing. Name of the book (in italics). Edition (if more than one). Place of publishing: Publisher. Permanent address. Reference day.
