RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents. Command-line tools allow interactive or scriptable access to the data which are stored in a SQL database. RefDB can also be accessed through a Web interface, a SRU interface, or via editor extensions (Emacs/vim). Libraries for Perl and PHP are available for programmers. RefDB provides sophisticated character encoding handling, using Unicode by default.
refbase is a Web-based bibliographic manager that can import and export references in various formats (including BibTeX, Endnote, ISI, RIS, PubMed, MODS XML, OpenOffice, and Word 2007 XML). It can make formatted lists of citations in HTML, RTF, PDF, or LaTeX, and offers powerful searching and RSS support. Its OpenSearch and SRU/W services and support for unAPI and COinS metadata allow for easy access by clients and search engines.
SimplyBibTeX is an application to share and hold BibTeX bibliographies. One can add, edit and remove entries from bibliographies online or upload complete collections.

scbib is a bibliography manager written in Scheme. It handles bibliographic data written in simple S-expressions and generates a bibtex file and an HTML file from the S-expressions file.

refdb-mode is a minor mode for Emacs that implements an interface to RefDB, a reference management and bibliography tool for SGML, XML, LaTeX, and Muse documents. It integrates nicely with psgml, nxml-mode, AucTeX, and muse-mode. refdb-mode provides the complete functionality of the RefDB command line clients from a graphical interface. You can add and edit references, notes, and styles, run queries, and insert the results as citations into your DocBook, TEI, LaTeX, or Muse documents. You can also look up cited references in the database right from your document. You can create, transform, and view these documents with a mouse click. This amounts to an integrated authoring environment for markup languages with reference management and bibliography support.
Aigaion is a Web-based shared bibliography manager built on PHP/MySQL. It is based on the BibTeX format, but has support for other formats as well.
