Abstract:

The package EASYBIB introduces new items for easy custom-made bibliographies.

The package EASYBIB

The scheme of the bibliography in the package EASYBIB was inspired by the bibliography system of A_MS-TEX. For the sake of flexibility, the syntax is somewhat different, yet 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 overrides the default thebibliography environment. In this case the environment thebibliography takes the form:

  
  \begin{thebibliography}``[optional name]''
                         ``(\cmd,space)''{99}
  .
  .
  .
  \end{thebibliography}

so that you can override the default name \refname with the name of your choice, you can change the default \section* with \cmd and add extra space space in front of 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     number of pages
  \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 may be 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 closes the definition of a reference. By default the reference is closed by the semicolum ;. 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{aaa}
\by     J. Free
\title  A book title
\publ   A publisher
\yr     1970
\endref

\bookref{bbb}
\by     B. New
\title  Another book title
\publ   Another publisher
\yr     1992
\endref

\bookref{ccc}
\by     C. Old
\title  Yet another book title
\publ   Again a publisher
\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 L^ATEX 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

Modifying the appearance

You can control the default formats by the command

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

for example

  \bibsetfmt[paper,by]{,}{\textit}{:}

This way you can easily modify the appearance of the bibliography.

Changing the order of the items

The order of 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 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 segment of 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 previous bibliography

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[.]
\end{thebibliography}
