    BibSonomy is a social bookmarking system as well as the underlying technical platform (which also is the basis for PUMA). The system enables users to share and annotate bookmarks and publications. The system is online since 2006 and is used by scientists all over the world to find, collect, manage, and cite scientific literature and to create and present publication lists. BibSonomy is publicly available and free to use.

    BibSonomy is run and developed by the DMIR Group in cooperation with the KDE group of the University of Kassel, and the L3S Research Center, Germany.

    You can follow news on BibSonomy in our blog or on Twitter.


    • Developer infos (source code, wiki) can be found at BitBucket.
    • For researchers we offer datasets (anonymized, regular snapshots of data, containing posts with users, resources, and tags)


    Here is a list of selected publications that discuss the system. For a full list, please see here.
