bibtexbrowser is a PHP script that creates publication lists from Bibtex files. [[#Download]]
=====Major features=====
* **(11/2009)** Optimize your presence on Google Scholar: bibtexbrowser generates [[http://www.monperrus.net/martin/accurate+bibliographic+metadata+and+google+scholar|Google Scholar metadata]]
* **(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.
* **(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 &#38;rss at the end of the URL)! [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=monperrus.bib&amp;all&amp;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&amp;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=====
* **(10/2009)** bibtexbrowser is able to generate a bibtex file containing only the selected entries (simply add &#38;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&amp;type=inproceedings&amp;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&amp;all|demo]]
* bibtexbrowser can display all entries for a given year [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;year=2004|demo]]
* bibtexbrowser can display a single bibtex entry [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib&amp;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&amp;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&amp;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')'' )

bibtexbrowser is a PHP script to browse and search bib entries from BibTex files. For instance, on the [[http://www.monperrus.net/martin/bibtexbrowser.php?bib=metrics.bib|bibtexbrowser demonstration site]], you can browse a bibtex file dedicated to software metrics. You can also embed a publication list in other pages, as in [[http://www.monperrus.net/martin/|my home page]].

You may modify the embedded CSS style.
There are two ways to tailor bibtexbrowser:
1/ change the embedded CSS style
2/ change the parameters ENCODING, PAGE_SIZE and co at the end of this documentation ~ line 120
You may modify the main parameters (e.g. ENCODING, PAGE_SIZE, etc ~ line 120)
You may modify the BibEntry::toString() method.
