Introduction : LaTex Footnote Package


An additional piece of information/details added at the bottom of any document is called Footnotes. In this section, we will learn how to add footnotes in LaTeX.

It is very simple and straightforward to add a footnote in any LaTeX document.

Command \footnote{...} is used to add the footnote in LaTeX. There is no need to add any package, it is by default supported in LaTeX.

Example of a footnote in LaTeX:

1
This is my first footnote article \footnote{www.resurchify.com}

The above command will append the superscript just after the word article and will print the corresponding footnote (In our e.g., www.resurchify.com will be printed as a footnote).

Basic usage of footnotes in LaTeX: Footnote URL/Anything


Now, let us look go in details and understand the basic usage of footnotes in LaTeX

To understand consider the below example to footnote URL/Anything

Future 5G cellular networks\footnote[1]{New Radio Cellular Networks}
are expected to support several-fold increase in data traffic and 
number of devices\footnotemark , and provide a very low latency 
and gigabit-rate data services.

\footnotetext{User Equipments}

The above example uses three different commands:

  • \footnote[1]{New Radio Cellular Networks} : This command will add the reference mark 1 and New Radio Cellular Networks as a footnote.
    Note: This command does not alter the footnote counter.
  • \footnotemark: This command will print the footnote mark but will not print the actual footnote. This footnote command allows you to write footnote text in the new line.
  • \footnotetext{User Equipments}: This command will print the footnote text User Equipments corresponding to the preceding \footnotemark


Footnotes with multiple references


LaTeX allows you to add multiple references to the single footnote mark. Consider the below example:

1

The future 5G cellular networks\footnote[1]{New Radio Cellular Networks}
are expected to support several-fold increase in data traffic and number 
of devices\footnotemark , and provide very low latency and gigabit-rate data services.

Considering this growth of data rates due to increased devices\footnotemark, 
we need  new technologies\footnotemark[\value{footnote}].

\footnotetext{footnote using two references}

Command \footnotemark[\value{footnote}] will print the subscript corresponding to the present value of \footnote counter.


How to Change the numbering style of Footnotes in LaTeX


In order to change the numbering style consider the below example:

1
2
3
4
\footnotetext{This is an example of changing the numbering style} 
 
\renewcommand{\thefootnote}{\alph{footnote}}
Now a footnote in alph\footnote{Footnote with alph style}

The supported numbering styles are as follows:

  • alph : Alphabetic lower case.
  • Alph : Alphabetic upper case.
  • arabic : Arabic numerals.
  • fnsymbol : A set of 9 special symbols.
  • Roman : Upper case Roman numerals.

Note: In order to change the number styling of the complete document, you need to include the above commands in the preamble of the document.
