dLibra 5.0 is still under intensive development. One of the most important things, that we are working on, is the user interface of the dLibra Readers Application. By changing old mechanism and adding new features, with extensive use of Web 2.0 approach, we are trying to improve user experience, of this most often used part of the dLibra system.
Recently we have modified the search mechanism and interface, in which we have previously implemented some important changes, like thumbnails in search results view. Currently we have also changed mechanism of selecting ambiguous synonyms values and filtering by collections. On the attached screen we can see the current result.

Selection of the ambiguous values is now visible on the left side of the search results page. For those, who have already used digital library based on the dLibra system, changes of values presentation can be noticeable; interface is also more friendly and intuitive. Other change allows a selection of more than one collection by which search results are narrowed.

We have also prepared some changes in content view interface. When viewing content on the bottom of the screen there is a new functional toolbar, in which there will be possibility to use few options from the user profile.

In relation to the previous version of dLibra there is also a change in view handlers selection – now each data format will have its default view handler and option of changing it to another (if possible) will be presented in the new toolbar.

The last thing, which is worth to mentioning, is some improvements to new publication creation mechanism in WWW application of the dLibra. New functionality was presented on dLibra Users Meeting at the PBC 2009 conference. Partly thanks to our users voices we have decided, before the dLibra 5.0 release, to prepare some improvements. One of attached screenshots shows the new interface of second step of publication creator.

Presented features are in test phase and can be changed before the final release. In the middle of August we are planning to stop the development of this dLibra version and start functional tests before the final release.
