Some months ago, Stephan presented BibSonomy's enhanced file upload feature which allows you to attach documents to your publication meta data - such as, e.g., a private copy of the paper or your own personal notes. In response to your feedback, we extended the list of supported file types which now encompasses the following file types:

• pdf for the Portable Document Format
• ps for PostScript files
• djv, djvu for scanned documents in the DjVu file format
• txt for plain text files
• doc, docx for Microsoft Word documents
• ppt, pptx for PowerPoint presentations
• xls, xlsx for Excel spreadsheets
• ods, odt, odp for documents, spreadsheets and presentations in the OpenDocument format

Please let us know, if your favourite file format is not supported.
Once again: Happy Tagging!

With some delay, today we upgraded BibSonomy to 2.0.16. We also updated our publicly available libraries at our Maven repository.
We are happy to announce, that this release includes the first version of a new major feature: Discussions and Reviews. We'll go into detail about that in our next blog post. But take a look at the stars you'll now find at the bottom right of every post and the new discussion link under each post.
Furthermore, new are:

• two new hidden system-tags: sys:unfiled and sys:jabRef:<someArgument>
  
• the extended functionality of the URL-parameter sortPage (sorting bookmarks is now possible)
  
• more allowed file types for your private document upload.
  

The next release is scheduled for July 27th.

Happy tagging!
Stephan
