       About &kbibtex;
     </title>
     <para>
       &kbibtex; is an integrated environment for creating and editing bibliographies in &bibtex; format. &kbibtex; gives you the ability to use all the functionalities of &bibtex; in a graphical interface, giving you easy, immediate, and customized access to local and online bibliographies with ability of entries completing, compiling, previewing and searching.

       <title>About &bibtex;</title>
       <para>
 	&bibtex; is a program and file format designed by Oren Patashnik and Leslie Lamport in 1985 for the &latex; document preparation system <citation>Lamport86</citation>.
       </para>
       <para>
 	The format is entirely character based, so it can be used by any program (although the standard character set for accents is &tex;). It is field (tag) based and the &bibtex; program will ignore unknown fields, so it is expandable. It is probably the most common format for bibliographies on the Internet.
       </para>
       <para>
 	The &bibtex; program uses style files, a list of citations from &latex;, and a &bibtex; database to create a &latex; file listing the cited references. The idea of style files is that final copy in any journal-specific form can be done automatically.
       </para>
       <para>

       Using the bibliography in your &latex; document

     <para>
       To actually use the bibliography in your paper, you need to add the following commands in your &latex; file (these commands are usually can be found at the end of the document - where the <quote>References</quote> section to appear):
     </para>
 <programlisting>
 \bibliography{<replaceable>foo</replaceable>}
 \bibliographystyle{plain}
 </programlisting>
     <para>
       Here, <replaceable>foo</replaceable> is the name of your <filename role="extension">bib</filename> file created with &kbibtex; and <quote>plain</quote> is the name of bibliography style.
     </para>
     <para>
       There is a plenty of specific bibliography styles. Please consult your publisher for the one to choose or try and find the one that suits the best for your purposes.
     </para>
     <para>
       Below is a list of some generic styles available everywhere:
     </para>
     <variablelist>
       <varlistentry>
 	<term>
 	  plain

 	  </para>
 	</listitem>
       </varlistentry>
     </variablelist>
     <para>
       So you can use your &latex; editor's capabilities (please consult the editor documentation for this) or just enter the following code in a generic text editor then save the file with <filename role="extension">tex</filename> name extension.
     </para>
 <programlisting>
 \documentclass{article}
  \begin{document}

 	Please save this file to the same folder as your <filename>example.bib</filename>.
       </para>
     </note>
     <para>
       Now that you have the basis for a document, you have to run both <application>latex</application> and <application>bibtex</application> to process it.
     </para>
     <para>
       First, you should run <application>latex</application> (to create a foo.aux file, which <application>bibtex</application> reads). Then run <application>bibtex</application> once to get some of the citations and create a <filename role="extension">bbl</filename> file. Then run <application>latex</application> again so that the cross references between the text file and the bibliography are correct. You may want to repeat running <application>bibtex</application> and <application>latex</application> on the file to make sure that all cross references are correct. Be warned that adding/deleting citations and sources will require running <application>bibtex</application> again.
     </para>
     <para>
       Thus, the following commands can be used to compile the document from console:
     </para>
     <screen>latex example
 bibtex example
 latex example
 latex example</screen>
     <tip>
       <para>
 	If you are using some advanced &latex; shell like &kile; or &lyx;, there is no need to worry about running all these commands from console emulator. Just use a hot key (<keycombo>&Alt;<keycap>6</keycap></keycombo> in &kile;) or a toolbar button to see the results.
       </para>
     </tip>
     <para>
-      Now, you can see the results as a &DVI; or &pdf; file (the format depends on your configuration), stored in the same folder as your source files.

 	  The simplest method to navigate in large bibliographies is to use the <guilabel>Filter</guilabel> toolbar: &kbibtex; will filter the displayed list according to your input.

 	</para>

 	  When you enter the first few letters, you will see the list changing. The more letters you enter, the more reduced list you will see. This filtering occurs immediately as you type.

 	<para>
 	  If you look at the right part of the <guilabel>Filter</guilabel> toolbar, you will notice two drop-down menus. The drop-down menus were designed for you to be able to quickly tailor filtering criteria to your needs. The first drop-down menu is used to define matching mode (<guimenuitem>any word</guimenuitem>, <guimenuitem>every word</guimenuitem> or <guimenuitem>exact phrase</guimenuitem>). The second is to define the field where the filtering should be done. You can choose <guimenuitem>any field</guimenuitem> or select a field to narrow down the list of the results in large bibliographies.

 	    &biblatex; is a reimplementation of &bibtex;. With &biblatex; the formatting of the bibliography is entirely controlled by &latex; macros, not <filename role="extension">bst</filename> files. It supports subdivided bibliographies, multiple bibliographies within one document, and separate lists of bibliographic shorthands. Bibliographies may be subdivided into parts and/or segmented by topics. Just like the bibliography styles, all citation commands may be freely defined. The &biblatex; package is completely localized and can interface with the babel package.<footnote><para>From &biblatex; documentation.</para></footnote>
