The digital environment has changed and new ICT has shaken librarianship. Digital resources have become essential tools for scholars and accordingly librarians need to be educated and well informed about all aspects of technology in order to help their users to formulate their information request, perform complex search of relevant information objects, interpret the results and locate what is in the physical property of certain library. For managing digital content, setting on information infrastructure is essential. Librarians use ICT but in most cases they don't understand them. With the changing role of librarians in the new environment raises the question of whether knowledge of what is „behind the system“ can contribute to improving the competence of the librarians in providing better services to its customers (for example in setting up quality modern education system). Perhaps learning about the „wheels that drive the system“ is not necessary for librarians to provide quality service but is certainly represents a challenge which overcome would surely bring many advantages. Poster will present free open source aplications like Wordpress, Drupal, Joomla, Moodle, Koha, Fedora (build on LAMP arhitecture) that can make use in digital scholary. Poster aim is to help understanding modern library infrastructure platform requiered for digital content publising, useage, scholary, management and preservation. The modern library needs a modern librarian that understands rapidly changing technology and can take full adventage of them.
