Pybliographer
Pybliographer is a reference management software tool that deals with bibliographic databases, used for viewing, editing, searching, and reformatting bibliographies. Written in Python and licensed under GNU GPL, it provides a scripting framework of classes and functions, which makes it extendable to many other applications.
In addition to the scripting environment, pybliographer provides a graphical GTK+-based interface called Pybliographic, allowing many customizable viewing and editing possibilities. The interface can also be used to insert references directly into LyX, Kile or OpenOffice.org, direct queries to Medline, and more.
