# Make volume bold in custom bibliography style .bst

Since I could not find the style that met my teacher's requirements for the bibliography I have to do, I created my own bst with latex makebst on my mac. I had chosen to make the volume bold but it does not appear in boldface on my document (I am using LyX). I was wondering if there is a way to make it appear in bold by modifying the bst file

This is what I have in the volume section

FUNCTION {format.bvolume}
{ volume empty${ "" } { bbl.volume volume tie.or.space.prefix "volume" bibinfo.check * * series "series" bibinfo.check duplicate$ empty$'pop$
{ emphasize ", " * swap$* } if$
"volume and number" number either.or.check
}
if$} FUNCTION {format.number.series} { volume empty$
{ number empty${ series field.or.null } { series empty$
{ number "number" bibinfo.check }
{ output.state mid.sentence =
{ bbl.number }
{ bbl.number capitalize }
if$number tie.or.space.prefix "number" bibinfo.check * * bbl.in space.word * series "series" bibinfo.check * } if$
}
if$} { "" } if$
}


Can someone help me solve this problem ? I tried to add {\bf } around * swap$* but it does not seem to be working. - Hello and welcome :) You can use backticks  to mark inline code fragments as I did in my edit. – Scott H. Nov 13 '12 at 0:19 Which "volume" concept do you refer to: That for a book (in a multivolume series, such as an encyclopedia), or that for a journal's volume? The BibTeX functions you display, format.bvolume and format.number.series, pertain to the former concept of "volume". If you're interested in the journal-related volume concept, you should be examining the function format.vol.num.pages. – Mico Nov 13 '12 at 0:22 I want to make the Journal volume in bold – esmitex Nov 13 '12 at 8:16 ## 1 Answer The language of BibTeX style is based on reverse Polish notation. This means that it puts strings on a stack and the functions operates on the last element(s) in the stack. Thus to make the current element of the stack bold, one can create the following function FUNCTION {makebold}{ "\textbf{" swap$ * "}" * }
}


This function assumes that there is an element on the stack, then it adds the string \textbf{ to the stack, thus after this step the stack is "element" "\textbf{". The instruction swap$ inverts the order of the last two elements in the stack. * replaces the last two elements with their concatenation. Thus after the first * the last element of the stack is "\textbf{element". Then we append "}" to the stack and finally we concatenate it with the previous element. Thus we obtain "\textbf{element}". After defining the function you can replace emphasize with makebold (or see the comment by Mico about the other relevant functions) - Thank you very much. I found out there was a bolden function in the ".bst" file at the top. I wrote bolden before swap$ instead of emphasize and I wrote bolden just before volume in format.vol.num.pages`. I don't know for sure which one is the right solution but it worked. –  esmitex Nov 13 '12 at 8:23
