Fine-tuning bibliography

Question

This question concerns fine-tuning a bibliography. I collected bib files (that are available for download from the source of a journal article) and put them all in a single biblio.bib file. Here are the files with a snippet of the biblio.bib file.

Preamble.tex

\usepackage[natbib=true,style=authoryear,backend=bibtex8]{biblatex}
\usepackage[margin=2.54cm,top=2.54cm]{geometry}
\usepackage{amscd, amsfonts, amsmath, amssymb, amstext}
\usepackage{accents}
\usepackage{hyperref}
\usepackage{graphicx}
\usepackage{epstopdf}

\addbibresource{biblio.bib}

% Used by included files to know they
% are NOT standalone
\usepackage{ifthen}
\newboolean{standaloneFlag}
\setboolean{standaloneFlag}{true}

%% Command to conditionally typeset a bibliography.
\newcommand{\standaloneBib}{%%
  \ifthenelse{\boolean{standaloneFlag}}%%
             {\printbibliography}{}} 

Master.tex

\documentclass[12pt]{report}
\usepackage{standalone}
\input{preamble}
\begin{document}

\setboolean{standaloneFlag}{false}

\input{indiv1}
\input{indiv2}

\printbibliography
\end{document}

Indiv1.tex

    \documentclass[12pt]{report}
    \usepackage{standalone}
    \input{preamble}

    \begin{document}


    \chapter{Solving \citeauthor{GreenwoodAER1988}\citeyearpar{GreenwoodAER1988} using Linear Quadratic Approximation}

    \end{document}

Indiv2.tex

\documentclass[12pt]{report}
\usepackage{standalone}
\input{preamble}
\begin{document}
\chapter{Solving \citeauthor{KKR2008}\citeyearpar{KKR2008}}

\standaloneBib
\end{document}

However, as you can see, the information provided in bib file by various journals are different from each other. The style also varies - {} and "" are used. I want to know whether "I can specify what information to be included in the appendix (after typesetting). I don't want to edit the bib files that I get from sources, if possible."

Answer 1

First, I wouldn't really bother my self with the styles of entries in the .bib file, bibtex allows different forms like "" or {}, with or without indentation...etc, it would be time consuming and pointless to modify each and every entry.

As far as I know, you can't comment a field within a bib entry, which would have been convenient in your case, so I suppose you could save your downloaded original bib files separately somewhere, and modify them within your to be compiled bib file.

Regarding the URL issue, you could simply use the following in your field:

@article{GoodArtcl,
  title={\href{www.articlegood.com}{The Good Article}},
  author={John Do}
}

Obviously, the first value in the \href command is the URL, the second is hypertext, shown as 'The Good Article', and linked to your chosen URL.

Regarding the bibliography style, I suggest you generate your own with makebst.tex, you'll have to compile it with LaTeX, which will ask you a series of questions regarding your preferences for the bibliography style.

Edit: Refer to Joseph's answer to the following question regarding suppressing particular fields: https://tex.stackexchange.com/a/23118/9241

P.S: This answer is partially a reply to an inquiry which has been removed from the original question; the URL issue.
