Removing the quotations marks from the bibliography using harvard style (agsm)

Question

I'm pretty new to using LaTeX but have so far found it fairly intuitive and am currently using it to write my dissertation. I am using the harvard and natbib packages to cite and create my bibliography.

I am using the agsm style to create the bibliography and end up with this:

Leopold, L. & Maddock, T. (1953), ‘The hydraulic geometry of stream channels and some physiographic implications’, U.S. Geological Survey Professional Paper 252, 1– 56.

As opposed to what I need being this:

Leopold, L. & Maddock, T. (1953), The hydraulic geometry of stream channels and some physiographic implications, U.S. Geological Survey Professional Paper 252, 1– 56.

I need to remove the quotation marks at the start and end of the contents of the title field, but I'm not sure how.

The BibTeX code for the reference is

@article{leopold1953,
 Author = {Leopold, L.B. and Maddock, T.},
 Date-Added = {2012-03-10 11:33:51 +0000},
 Date-Modified = {2012-03-10 12:14:58 +0000},
 Journal = {U.S. Geological Survey Professional Paper},
 Lccn = {gs53000079},
 Pages = {1-56},
 Series = {Professional paper},
 Title = {The hydraulic geometry of stream channels and some physiographic implications},
 Volume = {252},
 Year = {1953},
 Bdsk-Url-1 = {books.google.co.uk/books?id=cA%5C_WYgEACAAJ}
}

Answer 1

make yourself a copy of agsm.bst, and call it agsm-nq.bst (in the same directory as your document).

edit agsm-nq.bst, and search for the line with "FUNCTION {article}"

the start of the function is:

FUNCTION {article}
{ output.bibitem
  list.label.output
  " \harvardyearleft " list.year * "\harvardyearright " * output.nonnull
  author "author" item.check
  title.field field.used =
    { skip$ }
    { format.title quote "title" output.check }
...

in the last line, there, there's the function that puts the quote in. change the line to read:

    { format.title "title" output.check }

now change

\bibliographystyle{agsm}

to

\bibliographystyle{agsm-nq}

in your document, and the quotes won't be created.

you can do similar things to other reference types, if they too have that quote function in them
