This is a project I started one year ago and it has grown into an interesting publishing system. It was developed for the E-journal Ikaros as a module of the CMS Drupal and it is meant for the management of real electronic journals (peer reviewed possibly too). For demonstration of the features, see :
E-journal demo at http://ejournal.roman-chyla.net (please note, this is a new site, should be functional very soon - by the end of October 07)

The real, production site is at :

http://www.ikaros.cz - E-journal

And the module itself in the e-journal section at Drupal.
