There is a specific notation for each type of publication (book, journal article, online publication, etc.) when referred to in a note (see also Sample Citations)
All publications mentioned in your notes are also collected in your Bibliography. A bibliography contains the last names of the authors (in alphabetical order), followed by their first name or initials, separated by a comma. When a book has two or more authors, only the name of the first author is inverted, because this is the name that determines its alphabetical place in the list. There is no need to invert names in notes, as these are not ordered alphabetically.
If you refer to the same publication more than once in your notes, use the full title in your first reference only. Use a shortened reference in all subsequent notes.
At first mention, include the author’s/editor’s name, full title, publication facts and page number.
The second time, use only the author’s last name, a shortened title and the page number(s).
When referring to the same work in two consecutive notes, your second note can be even shorter. Just type ‘Ibid.’ followed by the page number (if different from your earlier reference), separated by a comma.
In short:
First reference to publication in documentary note: in full.
Second reference: short title (and page number(s))
Reference to same publication in consecutive notes: ‘Ibid.’ (plus new page number if applicable).
A single note can contain references to various publications. Use a semi-colon to separate individual publications. Never follow one sentence or clause by several note numbers, because this muddles the relationship with the source.
To indicate that the argument you are quoting is the subject of debate or that opinions vary in the publications you are quoting, use ‘Confer’, or rather ‘Cf.’, in the sense of ‘compare’.
