[Tex/LaTex] Biblatex bibliography title fields for different entries

biblatex

I'd like to typeset my bibliography (which currently contains > 100 entries) and I'm strongly considering using biblatex. I'd like to try some alternatives, being one of them printing the title of an entry in bold. To that end, following the suggestion on the usage of biblatex that another user gave me, I wrote the tex code below that uses \DeclareFieldFormat{title}{\textbf{#1}}. However I only get in bold the titles for books, manuals, miscs, technical reports, but this is ignored for articles, inproceedings and unpublished work.

Which is the field from those type of entries that I need to tune in biblatex in order to print their titles in bold?

\begin{filecontents*}{biblio.bib}
@ARTICLE{ar,
         author    = {Author-ar},
         title     = {ar}}
@inproceedings{inp,
         author    = {Author-inp},
         title     = {inp}}
@unpublished{unp,
         author    = {Author-unp},
         title     = {unp}}
@techreport{tr,
         author    = {Author-tr},
         title     = {tr}}
@misc{mi,
         author    = {Author-mi},
         title     = {misc}}
@MANUAL{ma,
         author    = {Author-ma},
         title     = {manual}}
@BOOK{bo,
         author    = {Author-bo},
         title     = {book}}
\end{filecontents*}

\documentclass{article}
\usepackage[backend=bibtex8]{biblatex}
\bibliography{biblio}
\DeclareFieldFormat{title}{\textbf{#1}}
\begin{document}
Hello ~\cite{ar,inp,unp,tr,mi,ma,bo}.
\printbibliography[title={References}]
\end{document}

As soon as you set custom field formats, i.e. \DeclareFieldFormat[article]{title}{\textbf{#1}} the version without optional parameter \DeclareFieldFormat{title}{\textbf{#1}} is only applicated to entry types which have no custom format yet: @book, @inproceedings etc. – but not @article!

The starred version \DeclareFieldFormat*{title}{\textbf{#1}} will set the field format for every entry type, and overwrite them if necessary.

[Tex/LaTex] How to get BibLaTeX-chicago use title case capitalization

Any automatic solution will have a hard time beating a human well-versed in the Chicago Manual of Style's headline-style capitalization rules. So you're probably better off formatting titles in your source file manually. Whenever the document language or bibliography format calls for sentence-style capitalization, it is relatively easy to apply with biblatex's \MakeSentenceCase macro.

That said you could write a new macro, say \MakeHeadlineCase, and apply it in the title formatting directives. Another approach is to use biber's sourcemap option. It supports regular expressions and modifies fields before biblatex even sees them, which means the solution is entirely style-independent.

A rough approximation to headline-style capitalization is implemented in the following source mapping. It uses the XML syntax of the biber configuration file biber.conf. You can also specify source mappings in the document preamble with biblatex's \DeclareSourcemap command.

<?xml version="1.0" encoding="UTF-8"?>
<config>
<sourcemap>
  <maps datatype="bibtex" map_overwrite="1">
  <map>
    <map_step map_field_source="TITLE"
              map_match="(^|\s)(\w+\S*w*)" map_replace="$1\u\L$2"/>
    <map_step map_field_source="TITLE"
              map_match="\-(\w+)" map_replace="\-\u\L$1"/>
    <map_step map_field_source="TITLE"
              map_match="(\s+|\-)(A(|n|nd|s|t)|F(or|rom)|I(n|s)|O(f|n|r)|T(he|o)|With)\b"
              map_replace="$1\L$2"/>
    <map_step map_field_source="TITLE"
              map_match="([:;]\s+)([a-z])" map_replace="$1\u$2"/>
  </map>
  </maps>
</sourcemap>
</config>

The first two steps capitalize words at the beginning of the string (^), after whitespace (\s) or following a hyphen (\-). The third map down-cases selected words after whitespace or a hyphen. The last map capitalizes words following a colon or semi-colon ([:;]).

Here's a self-contained example.

\documentclass{article}
\usepackage[backend=biber]{biblatex}
\usepackage{filecontents}

\begin{filecontents*}{biber.conf}
<?xml version="1.0" encoding="UTF-8"?>
<config>
<sourcemap>
  <maps datatype="bibtex" map_overwrite="1">
  <map>
    <map_step map_field_source="TITLE"
              map_match="(^|\s)(\w+\S*w*)" map_replace="$1\u\L$2"/>
    <map_step map_field_source="TITLE"
              map_match="\-(\w+)" map_replace="\-\u\L$1"/>
    <map_step map_field_source="TITLE"
              map_match="(\s+|\-)(A(|n|nd|s|t)|B(ut|y)|F(or|rom)|I(n|s)|O(f|n|r)|T(he|o)|With)\b"
              map_replace="$1\L$2"/>
    <map_step map_field_source="TITLE"
              map_match="([:;]\s+)([a-z])" map_replace="$1\u$2"/>
  </map>
  </maps>
</sourcemap>
</config>
\end{filecontents*}

\begin{filecontents*}{\jobname.bib}
@BOOK{Smith2003,
  title = {This is an off-the-hook book title, but it doesn't have a subtitle},

[Tex/LaTex] Some fields don’t show up or are missing formatting in the bibliography even though I have entries for them

See here for details on entering multiple authors.

To display the information you require, search for BibTeX styles (good survey here) that use the fields desired. You may find that styles specific to your area of study include the fields you are expecting.

Not all styles use information from every field. For cases where the majority of the bibliography is as desired, but a few references are missing information, you can use the note field, which is always appended to the bib entry. But this should be used sparingly.
