1.6. Footnotes
Footnotes should be avoided if possible. Necessary footnotes should be denoted in the text by consecutive
superscript letters. The footnotes should be typed single spaced, and in smaller type size (8pt), at the foot of
the page in which they are mentioned, and separated from the main text by a short line extending at the foot of
the column. The ‘Els-footnote’ style is available in this template for the text of the footnote.
