Abstract:

The package EASYBIB introduces some new items for easy customization of the bibliography.

The package EASYBIB

The scheme for the bibliography in the package EASYBIB was inspired by the beautiful bibliography system of AMS-TEX . Due to the necessity of flexibility, the syntax is a little bit different but the functionality is similar (although not identical). For the use, load the package using the usual syntax: 

  
  \documentclass{article}
  .
  .
  \usepackage[definethebibliography]{easybib}
  .
  .
The option \definethebibliography permits to override the default thebibliography environment. In this case the environment thebibliography take this form: 

  
  \begin{thebibliography}``[optional name]''
                         ``(\cmd,space)''{99}
  .
  .
  .
  \end{thebibliography}
so that you can override the default name \refname with your own name, you can change the default \section* with \cmd and add extra space space before the items. The syntax of the bibliography command is now the following 


\begin{thebibliography}{99}

\bookref{label name}
  \by        Author(s) name
  \bysame
  \title     Title of the book
  \bookinfo  ...
  \publ      publisher
  \publaddr  publisher address
  \pages     pages number
  \yr        year
  \lang      ...
  \transl    ...
\endref

\paperref{label name}
  \by        Author(s) name
  \bysame
  \title     Title of the book
  \transl    ...
  \jour      Journal name
  \toappear  ...
  \inbook    ...
  \publ      publisher
  \eds       ...
  \publaddr  publisher address
  \vol       volume
  \yr        year
  \pages     pages number
  \finalinfo ...
  \lang      ...
\endref

\end{thebibliography}

the command 


  \bookref``[display label]''{label} ... \endref
is used to refer to a book, while 

  \paperref``[display label]''{label} ... \endref
is used to refer to a paper.

When an item, for example \xxx, is encountered then the following text is expanded as follows 


  \xxx+text ==> punctation + 
                begin commands + 
		text + 
		end commands
where the punctation is displayed unless \xxx is the first displayed item. The default values for the items in the \bookref environment are the following

command punctation begin commands end commands
\by , \bfseries nothing
\bysame , $\vcenter{\vskip.5em\hbox{\verb*'\hbox to3em'}\vskip.2em \hbox{\verb*'{\hrulefill\hskip.1em}'}\vskip.5em}$ nothing
\title , \scshape nothing
\bookinfo , \rmfamily nothing
\publ , \rmfamily nothing
\publaddr , \rmfamily nothing
\pages , \rmfamily nothing
\yr , \rmfamily nothing
\lang nothing ( )
\transl , \rmfamily nothing

The default values for the items in the \paperref environment are the following

command punctation begin commands end commands
\by , \bfseries nothing
\bysame , $\vcenter{\vskip.5em\hbox{\verb*'\hbox to3em'}\vskip.2em \hbox{\verb*'{\hrulefill'}\vskip.2em \hbox{\verb*' \hskip.1em}'}\vskip.5em} $ nothing
\title , \itshape nothing
\transl , \rmfamily nothing
\jour , \rmfamily nothing
\toappear nothing (to appear )
\inbook , \rmfamily nothing
\publ , \rmfamily nothing
\eds nothing ( \@killglue, eds.)
\publaddr , \rmfamily nothing
\vol nothing \bfseries nothing
\yr nothing ( )
\pages , \rmfamily nothing
\finalinfo , \rmfamily nothing
\lang nothing ( )

The command \moreref

In the case of more than one reference of the same author or in the case of a series of papers or books on the same argument, it is sometimes useful to use the \moreref command. The syntax is the following 

  \paperref{label name} or \bookref{label name}
  items
  \moreref`[punctation]'{book or paper}
  items
  \moreref`[punctation]'{book or paper}
  .
  .    
  \endref
The effect is to use a single label reference for more than one book or paper. The optional command ``[punctation]'' can be used to change the default punctation ``;'' to something else for example you can use \moreref[, see also:]{book}.

The command \endref

The command \endref ends the definition of a reference. By default the reference is ended with the punctation ;. It is possible to change the default value as follows 

  \endref[punctation], for example \endref[.]
This is useful for the last reference, for example 


\begin{thebibliography}{99}

\bookref{ORTEGA}
\by     J.~M.~Ortega, W.~C.~Rheinboldt
\title  Iterative Solution of Nonlinear
        Equation in Several Variables
\publ   Accademic Press
\yr     1970
\endref

\bookref{aaa}
\by     C.~V.~Pao
\title  Nonlinear Parabolic and Elliptic Equations
\publ   Plenum Press \publaddr NY
\yr     1992
\endref

\bookref{ZEIDLER}
\by     E.~Zeidler
\title  Nonlinear Functional Analysis
        and its Applications I
\publ   Springer Verlag \publaddr NY
\yr     1986
\endref[.]

\end{thebibliography}

\begin{center}\vbox{\input{docbib.2} }\end{center}

The command \refstyle

There are many styles for display the labels of the bibliography. The standard LATEX way of changing the appearance is to modify the \@bibitem macro. A easiest way in EASYBIB is to use \refstyle before \begin{thebibliography}. The syntax is the following: 

  \refstyle{A} or \refstyle{B}  or  \refstyle{C}
the effect is to change \@bibitem as follows

command \@bibitem definition sample output
\refstyle{A} \def\@bibitem#1{#1.} 1.
\refstyle{B} \def\@bibitem#1{[#1]} [1]
\refstyle{C} \def\@bibitem#1{} nothing

An example of bibliography from AMS-TEX documentation

Changing the appearance

You can change the default formats by the command 

  \bibsetfmt[group name,item]{punctation}
                             {begin commands}
                             {end commands}
for example 

  \bibsetfmt[paper,by]{,}{\textit}{:}
In this way you can change in an easy way the appearance of the bibliography.

Changing the order of the items

The order or the items: 

  for `paper' group:
  by,bysame,title,transl,jour,toappear,
  inbook,publ,eds,publaddr,vol,
  yr,pages,finalinfo,lang
  
  for `book' group:
  by,bysame,title,bookinfo,publ,publaddr,
  pages,yr,lang,transl
can be changed defining the macro \paperlist and \booklist. For example in order to have the yr item displayed after pages item in the paper group define: 

  \def\paperlist{by,bysame,title,transl,jour,%
                 toappear,inbook,publ,eds,%
		 publaddr,vol,pages,yr,%
		 finalinfo,lang}

Citing

The following code 


\citestyle{A}
Cite mode A \cite{book:1,art:1,art:2}. \\
\citestyle{B}
Cite mode B \cite{book:1,art:1,art:2}. \\
\citestyle{C}
Cite mode C \cite{book:1,art:1,art:2}.

\begin{center}\vbox{\input{docbib.5} }\end{center}

for the following bibliography

\begin{center}\vbox{\input{docbib.7.tex} }\end{center}

Defining new styles

If you do not like the predefined styles paper and book you can easily define new ones. For example suppose you want to define a new style tales with the item \author, \title, \year with:

* \author
in smallcaps style surrounded by a box

* \title
in italic style

* \year
in bold style within (...)

you must follow the following steps

* define the list of items

  \def\taleslist{author,title,year}

* define the command ``talesref'' with the items

  \bibdefinestyles{tales}
it defines the items \author, \title, \year with the default format and the command \talesref.

* change the default formatting

  \bibsetfmt[tales,author]
    {,}
    {\setbox0\hbox\bgroup\scshape}
    {\egroup\fbox{\box0}}
  \bibsetfmt[tales,title]{}{\itshape}{}
  \bibsetfmt[tales,year]{}{\bfseries(}{)}

The following example (which uses [definethebibliography]) shows the effect: 


\def\taleslist{author,title,year}
\bibdefinestyles{tales}
\bibsetfmt[tales,author]{,}
  {\setbox0\hbox\bgroup\scshape}
  {\egroup\fbox{\box0}}
\bibsetfmt[tales,title]{}{\itshape}{}
\bibsetfmt[tales,year]{}{\bfseries(}{)}

\begin{thebibliography}[Tales](\section*,1cm){99}
   \talesref{A}
      \author Isaac Asimov
      \title  Nemesis
      \year   1989
   \endref
   \talesref{B}
      \author Roger Zelazny
      \title  Nove principi in ambra
      \year   1970
   \endref
   \talesref{C}
      \author Dean R. Koontz
      \title  Strangers
      \year   1986
   \endref[.]
