References should be cited in the text by last name and year in parentheses. For quotations, page number should be indicated after the year of the publication. The last name, year, and page number should be separated with commas.
The list of references should only include works that are cited in the text and that have been published or accepted for publication as well as papers presented at scientific conferences. Text citations and reference list entries should agree both in spelling and in date. Personal communications and unpublished works should only be mentioned in the text. Footnotes and endnotes should not be used as a substitute for a reference list.
