BibSonomy / Home


BibSonomy is a social bookmark and publication sharing system. It is developed and operated by the Data Science Chair of the University of Würzburg, the Information Processing and Analytics Group of the Humboldt-Universität zu Berlin, the KDE group of the University of Kassel, and the L3S Research Center, Germany.

News & Contact


BibSonomy has help pages in English and German but most of the functionality is described in our feature of the week series in the BibSonomy blog which we highly recommend to read.

The system has also been described in the research article The Social Bookmark and Publication Management System BibSonomy.

Integration with other Websites and Services

BibSonomy integrates well with other websites, content management systems, and reference managers. Furthermore, you can connect BibSonomy to your own software using one of our API (application programming interface) clients. This list describes ways to integrate BibSonomy with various systems and technologies - ranging from code snippets to complete and powerful, easy-to-install plugins or API clients.


BibSonomy is a Java-based web application, backed-up by a MySQL database and Elasticsearch for fulltext search.

Source Code


  • The API documentation describes the basic functionality of the REST-API. It presents the XML schema and contains examples. Newer features, like synchronization, are not described, yet. For that have a look at the classes in the package org.bibsonomy.model.logic in the bibsonomy-model module and use their implementation in the REST client.
  • You can have a look at some Java code samples or have a look at the bibsonomy-tools project which is also another good source of code samples. Users of other programming languages can also have a look at the REST client to see which URLs are called.
  • The BibSonomy post filter and a (yet to be finished) Python REST client for the BibSonomy API might be other good sources to play around with.




The development of BibSonomy is or was partially funded by the following projects:

PUMA - Akademisches Publikationsmanagement

Info 2.0 - Informationelle Selbstbestimmung im Web 2.0

TAGora - Semiotic Dynamics in Online Social Communities
