I am creating my document using online LaTeX editor overleaf. The Citation should be like this: [21].

When I use the nar bibliography style:

bibliographystyle{nar}

bibliography{sample-bibliography.bib}

I the reference looks like this:

[21]  Gallais,  J.  F.,  Kizhvatov,  I.,  and  Tunstall,  M.  (2011)  Im-

proved trace-driven cache-collision attacks against embedded

AES  implementations.  In Information  Security  Applications pp. 243–257 Springer.

But I want to remove the parentheses around the year, to make it look like this:

[21]  Gallais,  J.  F.,  Kizhvatov,  I.,  and  Tunstall,  M.  2011  Im-

proved trace-driven cache-collision attacks against embedded

AES  implementations.  In Information  Security  Applications pp. 243–257 Springer.

How to remove the parentheses around year in the references?

Is there any other style can I use for above citation [21] and reference style?

You'll need to make a copy of the nar.bst file in the same folder as your main .tex file and edit it.

The relevant code is the format.date function around line 375 of nar.bst. The original function is:

FUNCTION {format.date}

{ year empty$

    { month empty$

    { "" }

    { "there's a month but no year in " cite$ * warning$

      month

    }

      if$

    }

    { month empty$

%   'year originally

    {"(" year ")" * * } % TDS

    {"(" month ", " year ")" * * * * } % TDS

      if$

    }

  if$

}

The line that adds the parentheses to the year is:

{"(" year ")" * * } % TDS

to remove the parentheses, change it to:

{ year } % TDS

However, if your bib entry contains a month field, then the line that prints the date is the next one:

{"(" month ", " year ")" * * * * } % TDS

if you want to remove the parentheses from here as well, then you have to change it to:

{ month ", " year * * } % TDS

which will print as month, year. If you want another format let me know and I'll add it.

The function, after the edits, will be:

FUNCTION {format.date}

{ year empty$

    { month empty$

    { "" }

    { "there's a month but no year in " cite$ * warning$

      month

    }

      if$

    }

    { month empty$

%   'year originally

    { year } % TDS

    { month ", " year * * } % TDS

      if$

    }

  if$

}

Just replace that in your copy of nar.bst and it'll do. For your convenience, here's the edited version: https://pastebin.com/76Lhhr8U

Output:

I am using bibliographystyle{dcu} for Harvard style citation, I also want to get rid of the parenthesis from the dcu.bst file. How can I remove the () parenthesis around the year that appears in the reference list? I am asking because I am not seeing the parenthesis around a year in the source code i.e, dcu.bst file.

You can find the code here: http://tug.ctan.org/tex-archive/macros/latex/contrib/harvard/dcu.bst

Thank you for your help in advance.
