You can find the Google Chrome extension on the Chrome Web Store. For addition information, a full set of features and the possibility to request further features or report bugs, please refer to our Bitbucket repository, where the source of the extension is also openly available.
Since this is the first release of BibSonomy Scholar, there might still be some rough edges and bugs. Thus, we would greatly appreciate feedback and ideas to further enhance this extension. Nevertheless we hope that you enjoy the provided features and find BibSonomy Scholar as useful as we do. Have fun using it!
