Release 3.0.0

Today we released version 3.0.0. We fixed several bugs in the new layout and migrated some features from the old to the new layout (e.g. you can edit the tags of your posts in the post list again). Furthermore, we improved several web scrapers and added a new scraper for Akadémiai. We also fixed some minor bugs in the core system to provide a better user experience and system performance.

We are happy to announce that all BibSonomy modules are now open source. You can find the source code on Bitbucket. Moreover, you can find all compiled modules in our Maven repository ( including a source distribution.

Happy tagging,

Release 2.0.47

Hello BibSonomy folks,

today marks the release of BibSonomy 2.0.47. We integrated a new publication scraper for the WorldScience Journal. We also fixed the Arxiv scraper, which should now be working properly again. As for the last two releases, we worked hard on the new layout (also see our previous blog post for this). The layout is now in open beta. As a small change, we fixed a small issue with the maximum number of posts you can view at one time.

Be a part of the BibSonomy 3 Beta Program

As announced a few weeks ago, we are working on a new front-end for BibSonomy. The new user interface is also the main component of the release of BibSonomy 3.

Be a part of the BibSonomy 3 Beta Program

BibSonomy 3 will be available this fall. We’re very interested in the opinion of our users and therefore we would like to invite you to try BibSonomy 3 now. The Beta Program lets you take part in shaping it by test-driving the pre-release version and letting us know what you think.

To join the BibSonomy 3 Beta Programm, just sign-in to BibSonomy and go to, read the user hints and press the button at the bottom of that page. When you come across an issue, you can report it in our bug tracker. If you would like to give us more general feedback, you can leave a comment for this post.

BibSonomy 3 is currently in beta status and still in development, which means some features and services might not always work as expected. At any time, it is possible to switch back to the BibSonomy 2 front-end on

We are grateful for your feedback! 

So long, keep tagging,

Your BibSonomy Crew

Feature of the Week: BibSonomy and Memento

Over the past weeks, the Memento team has worked with colleagues at BibSonomy to enable Memento-related functionality for BibSonomy bookmarks. The Memento "Time Travel for the Web" protocol specified in RFC 7089 extends the HTTP protocol with datetime negotiation, a variant of content negotiation. A Memento client requests an old version of a resource by expressing the resource's original URI along with the datetime of the version it is interested in. A Memento server, such as a web archive, responds with an archived snapshot of the resource that is temporally closest to the datetime requested by the client. A Memento Aggregator simultaneously polls multiple web archives and returns the temporally closest snapshot available irrespective of the archive it resides in.

Two features that use Memento infrastructure were added for BibSonomy Bookmarks:
  • Bookmarked links are annotated with a data-versiondate attribute that conveys the datetime of bookmarking. This attribute, as well as the related data-versionurl, were first proposed in the Memento-related Missing Link document that explores annotating links with temporal information as a means to increase link robustness and to allow revisiting linked resources as they were seen by the creator of a link. Both attributes make use of an extensibility mechanism offered by HTML5 that allows the introduction of private data- attributes. The Memento extension for Chrome supports both attributes. For bookmarked links in BibSonomy, the extension presents a menu item Get at link date ..., which allows to look for archived snapshots of the bookmarked page from around the time it was bookmarked. This feature is demonstrated in the below image. At the left hand side, a user clicks the link to the website of the Raw visualization tool and receives the current version of the page in response. At the right hand side, a user right-clicks the same link in a Chrome browser that has the Memento extension installed. Since that link is annotated with the datetime of bookmarking - expressed as the attribute data-versiondate="2014-03-16T17:42:12+01:00" on the link - the Memento extension uses the provided date for web time travel and tries to find the archived snapshot of the Raw site closest to the date of bookmarking. It finds a snapshot dated March 7 2014 in the web archive that looks rather different than the current version.
  • The same functionality is available without the Memento extension for Chrome by clicking the little clock at the bottom of the bookmarked item. Doing so initiates a request by a Memento client at the end of BibSonomy that is targeted at the Memento Aggregator and that results in a redirect to a temporally appropriate Memento.

Both features are really neat and I would like to thank Robert Jäschke and his colleagues at BibSonomy for making this happen and Martin Klein at the Memento end for initiating the collaboration!

As we are about to release a new design for BibSonomy, we would like to show you a bit of the beginnings of our system. When it started out in 2006 the website looked a lot like today and still totally different:

The first publication on BibSonomy was also published in 2006 as was the very first blog post.

At the moment we are testing the new bootstrap layout, which will hopefully be released soon:

So stay tuned and keep tagging!

  • MDPI (
  • Oxford Journals (
  • The Lancet (

Aside from this, we fixed a number of small bugs such as a bug with tag recommendations. We updated the JabRef layouts and worked hard on the new layout. The layout is still in closed beta and will see its release in a future version.

Feature of the Week: Developers Corner

As part of our process to open BibSonomy up for developers, we have re-designed the BibSonomy start page at Bitbucket:
The three blue boxes provide quick access to pages about developing for and with BibSonomy, integrating BibSonomy with other tools and services, and using BibSonomy for research. They help you to easily find the information you need. The three grey boxes at the bottom provide further information, e.g., news about BibSonomy, who's behind BibSonomy, and where to find help.
In addition, the API documentation has been greatly improved during the last weeks. All developers definitely should have a loon on it and on the other relevant wiki pages.

Have a look at the new page and as always ... happy tagging!

BibSonomy gets a new front-end

We're currently working hard on a new user interface for BibSonomy. In the past, we've had lots of hints on how to optimize the layout, accessibility, and usability. We're scientists and programmers but we aren't product designers or experts of human computer interaction. So we've decided to use a framework that helps us to implement all these necessary improvements.

There are lots of front-end frameworks out there. We’ve chosen Bootstrap for the following reasons:

  1. Bootstrap is open source and freely available
  2. It supports responsive web design. It is very hard for a community of an open source project to develop and maintain two front-ends. With Bootstrap we develop code once-only and it works for computer screens, tablets (like the iPad), and smartphones
  3. Bootstrap is widely used. The look and feel of all elements is familiar. 
  4. And of course, it looks great ☺

The aim of a new front-end is to achieve an easier way to interact with BibSonomy. For this, we’ve defined a few rules, which we try to implement with the switch to Bootstrap.

  1. Give  all elements room to breathe! Currently, there are too many control elements spread over areas that are too small.
  2. Use larger fonts! Large fonts create larger clearness and better readability on mobile devices.
  3. If possible, use existing standard elements of Bootstrap. The elements of Bootstrap are approved and established. They are tested on different devices and browsers.
  4. Help the user where he/she needs help. With the last front-end redesign, we have added a lot of help and hints. Now we want to use it so it supports the user even better.
  5. Keep navigation menus clear. Easier menu structures helps users to find what they are looking for.

Finally, I would like to give you some insights in the new front-end:

post list and the new user menu

friends overview page

Mobile view

Tablet view

View for computer screens
We hope you like what you see. More information and release dates coming soon.

Keep happy and tagging!

Feature of the Week: Clipboard for beginners

This week we want to introduce some features offered by our clipboard that some of you might not know yet. The clipboard enables you to collect a subset of your own and other's publications. To add publications to the clipboard you can simply use BibSonomy's clipboard button as shown below: 

Once you've added all publications of interest to the clipboard you can export them using a format like MS Office XML, which was introduced last week. 

Another feature of the clipboard which is only available for your own publications is the adding of tags to multiple publications. You get there by clicking "edit own entries" in the above figure.

For example, if you want to collect publications as relevant literature for a paper, a class or a project, you can mark these publications in the clipboard by adding a meaningful tag to them.

Happy tagging!
