<?php /* bibtexbrowser: publication lists with bibtex and PHP
|
|
<!--this is version v__MTIME__, see http://www.monperrus.net/martin/bibtexbrowser/ -->
|
|
|
|
bibtexbrowser is a PHP script that creates publication lists from Bibtex files.
|
|
bibtexbrowser is stable, mature and easy to install. It is used in [[users|50+ different universities]] around the globe.
|
|
|
|
+++TOC+++
|
|
|
|
=====Major features=====
|
|
* **(11/2009)** bibtexbrowser generates [[http://www.monperrus.net/martin/accurate+bibliographic+metadata+and+google+scholar|Google Scholar metadata]] so as to improve the visibility of your papers on Google Scholar. Since Google has now [[http://scholar.google.com/intl/en/scholar/inclusion.html|documented this feature]], as of version ≥20100621, Google Scholar Metadata should be completely correct.
|
|
* **(11/2009)** More and more academics use bibliographic software like [[http://www.zotero.org/|Zotero]] or [[http://www.mendeley.com/|Mendeley]]. bibtexbrowser generates [[http://ocoins.info/|COinS]] for automatic import of bibliographic entries with [[http://www.zotero.org/|Zotero]] and [[http://www.mendeley.com/|Mendeley]].
|
|
* **(10/2009)** People can subscribe to the RSS publication feed of an individual or a group so as to being kept up-to-date: bibtexbrowser generates RSS feeds for all queries (simply add &rss at the end of the URL)! [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=monperrus.bib&all&rss|demo]]
|
|
* **(02/2009)** bibtexbrowser can display all entries for an author with an academic style (i.e book, articles, conference, workshop): [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&academic=Ducasse|demo]]
|
|
* **(05/2008)**: bibtexbrowser can be used to embed a publication list into another page: [[http://www.monperrus.net/martin/|demo]]
|
|
* **(04/2007)**: bibtexbrowser is easy to install: just a single file.
|
|
|
|
=====Other features=====
|
|
* **(10/2010)** bibtexbrowser now supports cross-references (Bibtex crossref)
|
|
* **(09/2010)** bibtexbrowser now supports multiple bibtex files (''bibtexbrowser.php?bib=file1.bib;file2.bib'')
|
|
* **(05/2010)** bibtexbrowser adds links to your co-author pages if you define the corresponding @string (see function addHomepageLink)
|
|
* **(01/2010)** bibtexbrowser can handle user-defined bibliographic styles
|
|
* **(10/2009)** bibtexbrowser is able to generate a bibtex file containing only the selected entries (simply add &astext at the end of the link)
|
|
* **(10/2009)** bibtexbrowser is now independent of the configuration of register_globals
|
|
* **(01/2009)** bibtexbrowser allows multi criteria search, e.g. [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&type=inproceedings&year=2004|demo]]
|
|
* bibtexbrowser replaces constants defined in @STRING
|
|
* bibtexbrowser is very fast because it keeps a compiled version of the bibtex file (PHP object serialized)
|
|
* bibtexbrowser is compatible with PHP 4.x and PHP 5.x
|
|
* bibtexbrowser can display the menu and all entries without filtering from the file name passed as parameter [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib|demo]]
|
|
* bibtexbrowser can display all entries out of a bibtex file [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&all|demo]]
|
|
* bibtexbrowser can display all entries for a given year [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&year=2004|demo]]
|
|
* bibtexbrowser can display a single bibtex entry [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&key=monperrus08d|demo]]
|
|
* bibtexbrowser can display found entries with a search word (it can be in any bib field) [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&search=ocl|demo]]
|
|
* bibtexbrowser can display all entries with a bib keyword
|
|
* bibtexbrowser outputs valid XHTML 1.0 Transitional
|
|
* bibtexbrowser can display all entries for an author [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&author=Barbara+A.+Kitchenham|demo]]
|
|
* bibtexbrowser can be used with different encodings (change the default iso-8859-1 encoding if your bib file is in utf-8 ''define('ENCODING','utf-8')'' )

=====Demo and screenshot=====
|
|

Demo: [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib|Here, you can browse a bibtex file dedicated to software metrics]]
|

|
<a href="bibtexbrowser-screenshot.png"><img height="500" src="bibtexbrowser-screenshot.png" alt="bibtexbrowser screenshot"/></a>
|
|
|
|
=====Basic installation=====
|
|
|
|
Create a bib file with the publication records (e.g. csgroup2008.bib) and upload it to your server.
|
|
* Use the link ''bibtexbrowser.php?bib=csgroup2008.bib'' (frameset based view)
|
|
* Use the link ''bibtexbrowser.php?bib=csgroup2008.bib&all'' (pub list sorted by year)
|
|
* Use the link ''bibtexbrowser.php?bib=csgroup2008.bib&all&academic'' (pub list sorted by publication type, then by year)
|
|
|
|
** Warning **: bibtexbrowser maintains a cached version of the parsed bibtex, for high performance, check that PHP can write in the working directory of PHP.
|
|
|
|
=====Handling mutliple bibtex files=====
|
|
|
|
It is a common practice to create one file for the @string, and another one with the bib entries. In this case, just give bibtexbrowser the files separated by a semi-column e.g:
|
|
|
|
''bibtexbrowser.php?bib=strings.bib;csgroup2008.bib''
|
|
|
|
|
|
=====How to embed your publication list in your home page=====
|
|
|
|
<table border="1">
|
|
<tr><th></th><th>Sorted by year </th><th>Sorted by publication type</th></tr>
|
|
<tr><td>For a group/team/lab</td>
|
|
<td>
|
|
<?php
|
|
$_GET['bib']='csgroup2008.bib';
|
|
$_GET['all']=1;
|
|
include( 'bibtexbrowser.php' );
|
|
?>
|
|
</td>
|
|
<td>
|
|
<?php
|
|
$_GET['bib']='csgroup2008.bib';
|
|
$_GET['all']=1;
|
|
$_GET['academic']=1;
|
|
include( 'bibtexbrowser.php' );
|
|
?>
|
|
</td>
|
|
</tr><!-- end group -->
|
|
<tr><td>For an individual</td>
|
|
<td>
|
|
<?php
|
|
$_GET['bib']='mybib.bib';
|
|
$_GET['author']='Martin Monperrus';
|
|
include( 'bibtexbrowser.php' );
|
|
?>
|
|
</td>
|
|
<td>
|
|
<?php
|
|
$_GET['bib']='mybib.bib';
|
|
$_GET['author']='Martin Monperrus';
|
|
$_GET['academic']=1;
|
|
include( 'bibtexbrowser.php' );
|
|
?>
|
|
</td>
|
|
</tr><!-- end individual -->
|
|
</table>
|
|
|
|
And tailor it with a CSS style, for example:
|
|
<style>
|
|
.date { background-color: blue; }
|
|
.rheader { font-size: large }
|
|
.bibref { padding:3px; padding-left:15px; vertical-align:top;}
|
|
.bibtitle { font-weight:bold; }
|
|
.bibbooktitle { font-style:italic; }
|
|
</style>
|
|
|
|
=====How to tailor bibtexbrowser?=====
|
|
|
|
====By modifying the CSS====
|
|
|
|
If bibtexbrowser.css exists, it will be used, otherwise bibtexbrowser uses its own embedded CSS style (see function bibtexbrowserDefaultCSS).
|
|
|
|
====By modifying the configuration parameters====
|
|
|
|
All configuration parameters are of the form ''define("PARAMETER_NAME","PARAMER_VALUE")'' at the beginning of the script. You can modify them by creating a file named "bibtexbrowser.local.php" containing the modified value. For instance:
|
|
|
|
<code>
|
|
<?php
|
|
@define("ENCODING","utf-8");// if your bibtex file is utf-8 encoded
|
|
?>
|
|
</code>
|
|
|
|
|
|
<a name="modify-bibstyle"/>
|
|
====By modifying the bibliography style ====
|
|
The bibliography style is encapsulated in a function. If you want to modify the bibliography style, you can copy the default style ([[bibtexbrowser-style-default.php.txt|source]]) in a new file, say ''bibtexbrowser-yourstyle.php'', and rename the function ''DefaultBibliographyStyle'' in say ''MyFancyBibliographyStyle''.
|
|
Then, add in the file ''bibtexbrowser.local.php'':
|
|
<code>
|
|
<?php
|
|
include( 'bibtexbrowser-yourstyle.php' );
|
|
define('BIBLIOGRAPHYSTYLE','MyFancyBibliographyStyle');
|
|
?>
|
|
</code>
|
|
|
|
[[http://www.monperrus.net/martin/bibtexbrowser-style-janos.php.txt|Janos Tapolcai contributed with this style, which looks like IEEE references]].
|
|

|
|
|
|
=====How to add links to the slides of a conference/workshop paper?=====
|
|
|
|
You can simply fill the ''comment'' field of the bib entry with an HTML link:
|
|
<code>
|
|
@inproceedings{foo,
|
|
author="Jean Dupont",
|
|
title="Bibtexbrowser",
|
|
year=2009,
|
|
booktitle="Proceedings of the BIB conference",
|
|
comment={<a href="myslides.pdf">[slides]</a>}
|
|
}
|
|
</code>
|
|
|
|
|
|
|
|
|

|
Unlike them, **bibtexbrowser is dynamic**.i.e.; generates the HTML pages on the fly. Thus, you do not need to regenerate the static HTML files each time the bib file is changed.
