bib2xhtml - BibTeX bibliography to XHTML converter
bib2xhtml [ -a ] [ -b bibtex-options ] [ -c ] [ -D mappings ] [ -d delimiter ] [ -e extended-information ] [ -h heading ] [ -i ] [ -k ] [ -m macro-file ] [ -n author-name ] [ -r ] [ -s style ] [ -t ] [ -v ] [ -u ] sourcefile [ htmlfile ]
bib2xhtml converts a bibtex-format bibliography file to XHTML. sourcefile may be either a BibTeX-format bibliography (.bib) file or a LaTeX-fomatted bibliography auxillary file (.aux). htmlfile will often be just part of a larger XHTML file; bib2xhtml attempts to update the XHTML file in place. It does this by searching htmlfile for two special strings, which delimit the bibliography part of the file. These strings are the XHTML comments
<!-- BEGIN BIBLIOGRAPHY delimiter -->
<!-- END BIBLIOGRAPHY delimiter -->
If these delimiters are found, the old bibliography between them is replaced with the new bibliography. Otherwise the new bibliography, with the appropriate delimiters, is appended to the end of htmlfile, and it will be necessary to move it to the proper location by hand. Note that it is possible for htmlfile to contain any number of bibliographies, and they may be updated independently. If no htmlfile is specified, the bibliography is written to standard output.
The tag of each BibTeX bibliography entry is converted into a name anchor (<A NAME="tag">) in htmlfile, and may be used to construct a link to this particular entry.
By default the contents of the bibliography are determined by the contents of the sourcefile. It is also possible to specify the contents of the bibliography in the htmlfile itself by setting the -i option and using two special strings to delimit the citations to be used for generating the bibliography. These strings are the XHTML comments
<!-- BEGIN CITATIONS delimiter -->
<!-- END CITATIONS delimiter -->
If these delimiters are found, the contents between them are searched for XHTML comments containing the citations (one citation per line), for example
<!-- BEGIN CITATIONS delimiter -->
<!--
\citation{knuth:1997}
\citation{knuth:1984} -->
<!-- END CITATIONS delimiter -->
These citations are then used for choosing the bibliography entries from the sourcefile.
Special
Field Processing
Several BibTeX fields are treated specially. The filenames
specified in the postscript, pdf, and
dvi fields are relative to the htmlfile
directory. In addition, bib2xhtml recognizes
compressed or gzipped files (those with filenames ending in
.Z, .gz, or .z).
|
url |
If the url field exists, a link (‘‘A’’ tag) is created. The destination of the link is the url tag’s value. The bibliography entry’s title is the source of the link. This can be used to create a link to a XHTML version of the paper, or to a version that is available by ftp. | ||
|
mailto |
If the mailto field exists, a link (‘‘A’’ tag) is created. The destination of the link is the mailto tag’s value. The bibliography entry’s author name is the source of the link. |
postscript
If the postscript field exists, its value is used as the name of a PostScript file. bib2xhtml creates a link to the file, and updates htmlfile with the number of pages and size of the PostScript file.
|
doi |
If the doi field exists, its value is used as the designation of a digital object identifier. bib2xhtml creates a link to the object through http://dx.doi.org and updates htmlfile with the doi as a hyperlink. The doi should normally be in a canonical form like the following: doi:10.1145/363347.363387. However, if the doi designator is formed as an HTTP hyperlink, it will be converted to the canonical form by replacing the HTTP protocol designation and the host name of the hyperlink with the doi: literal string. | ||
|
|
If the pdf field exists, its value is used as the name of a PDF (portable document format) file. bib2xhtml creates a link to the file and updates htmlfile with the size of the PDF file. | ||
|
dvi |
If the dvi field exists, its value is used as the name of a TeX DVI file. bib2xhtml creates a link to the file and updates htmlfile with the number of pages and size of the DVI file. |
author, keywords
The full author and keywords fields of each BibTeX entry are included in htmlfile as XHTML comments, and may be used by CGI scripts (such as bibsearch, which is supplied) to select only certain entries.
Hints
bib2xhtml’s LaTeX to XHTML conversion is not very
smart. If something isn’t being converted correctly,
try doing it in a different way.
bib2xhtml does not currently understand \verb. To get a tilde into a filename or an embedded URL, use \~{}. On the other hand, entries containing URL fields or \url{} commands, are correctly converted into hyperlinks. Leave such hyperlinks as they are; do not embed any LaTeX commands in them.
The lists that bib2xhtml generates contain CSS hooks of the class bib2xhtml. You can therefore modify the appearance of the lists by adding style entries like the following in the web page’s header.
<style type="text/css">
dl.bib2xhtml dd { padding-bottom: 1em }
</style>
<style type="text/css">
ul.bib2xhtml li { padding-bottom: 1em }
</style>
The value of the named attributes can contain arbitrary HTML markup commands, and can thus be used for substituting the text with icons. For example, the following Unix command can be used for creating stand-alone PDF icons.
perl bib2xhtml -e ’nosize,nopages,PDF:<img src="pdficon_small.gif"
alt="PDF" border="0" />’ example.bib example.html
Unser the Windows shell the corresponding command would be.
perl bib2xhtml -e "nosize,nopages,PDF:<img src=’pdficon_small.gif’
alt=’PDF’ border=’0’ />" example.bib example.html
A couple of PDF icons and the conditions for their use are available at http://www.adobe.com/misc/linking.html#pdficon .
To display the number of pages in local PDF files, the Perl module PDF::API2 must be installed on the system where bib2xhtml is running. A command like the following will accomplish this.
perl -MCPAN -e "install PDF::API2"
|
-a |
Include the BibTeX file’s abstract field in the bibliography. |
-b bibtex-options
Provide the specified options to the BibTeX program.
|
-c |
Sort chronologically. Normally, the bibliography is ordered first by author and then by date. With this option, the bibliography is ordered by year, month, day, and then by author. |
-d delimiter
Specify the delimiter that sets the bibliography off from the rest of the XHTML file. The default delimiter is the name of the bibliography file with the .bib extension stripped.
-D mappings
Define URL to directory mappings. The mappings argument contains a sequence of comma-separated values. Each value contains a local file path and the corresponding URL, separated by an @ sign. The resulting URL is used for linking the various paper file format types.
-e extended-information
Specify how an entry’s extended information will be displayed. The extended information is specified as a series of comma-separated attributes. The following plain attributes are supported.
|
notype |
Do not display the file’s type (PDF, Postscript, DVI). | ||
|
nosize |
Do not display the file’s size in bytes. |
nopages
Do not display the file’s number of pages.
nocompression
Do not display the file’s compression type.
|
nodoi |
Do not display the file’s DOI. |
nobrackets
Do not enclose the DOI link or the file’s extended information in brackets.
A number of valued attributes allow the specification of the text to display for various file types. These are written as a name:value pair. The following names are supported for valued attributes.
|
• |
PostScript |
|||
|
• |
|
|||
|
• |
DVI |
|||
|
• |
DOI |
-h heading Use the string heading instead of the default title when creating a new htmlfile. If updating an existing htmlfile, this option is ignored.
|
-i |
The citations are included in the htmlfile. When this option is set, the sourcefile must be a .bib file. | ||
|
-k |
In labeled styles (alpha, named, plain, and unsort) append to the label of each entry its BibTeX key. Thus, the label of each entry will consist of the original label, followed by an em-dash, followed by the BibTeX key. |
-m macro file
Specify a BibTeX macro file to supply to BibTeX when processing the bibliography file. Macro files typically contain local abbreviations and other macro definitions.
-n author name
Specify an author name to highlight. Any bibliography entry author names that match the name specified as a regular expression will be set in HTML strong tags and will therefore be displayed in a bold (or similar) font.
|
-r |
Reverse the chronological sorting order. Normally, the bibliography is sorted (by year; BibTeX ignores the month) from the earliest entry to the latest entry. With this option, the order is reversed. Note that to obtain a bibliography ordered by chronological order you must also specify the -c option. |
-s style
Create a style-style bibliography. Supported styles are empty (the default), plain, alpha, named, paragraph, unsort, and unsortlist. An empty bibliography is a bulleted list. A plain bibliography is a numbered list. paragraph produces just paragraphs (no bullets). unsort is like plain except that the entries in the XHTML file are in the same order as as they are in the source file. unsortlist is like unsort but entry labels are bullets instead of numbers. An alpha bibliography has labels that are in the BibTeX alpha style. A named bibliography has labels of the form [name, year].
|
-t |
Write a timestamp with the date at which the bibliography was updated to htmlfile. | ||
|
-v |
Report version number on stderr. | ||
|
-u |
Convert LaTeX special characters into the corresponding Unicode characters, and output XML coded in UTF-8. The output produced by this option may be easier to parse and validate with some XML parsers. By default LaTeX special characters are converted into HTML character entities. |
|
html-a.bst |
alpha XHTML BibTeX style file |
|||
|
html-n.bst |
named XHTML BibTeX style file |
|||
|
html-u.bst |
unsort XHTML BibTeX style file |
html-aa.bst, html-na.bst, html-ua.bst
versions of the above style files with abstracts
|
bibsearch |
a CGI script for performing bibliography searches |
perl(L), bibtex(L).
The LaTeX to XHTML translation, while decent, is not perfect.
Requires bibtex and perl. However, I think that most sites that would want to convert BibTeX to XHTML will already have both programs installed.
Relies on dviselect to count the number of pages in a DVI file.

The program was originally written as bib2html by David Hull in 1996, who maintained it until 1998 (version 1.33). In 2002, due to the lack of visible updates on the web, the program was adopted for maintenance, distribution, and further evolution by Diomidis Spinellis. Changes made by him include support for XHTML 1.0 and documentation bug fixes. The first public release of the maintenance effort was in 2004 (version 2.1). On March 2004 the program was renamed into bib2xhtml to avoid confusion with projects using the name bib2html . Panos Louridas ([email protected]) added the functionality for including the citations in the htmlfile .
