TracciarisorseOpen Short Guide

It is a directory by subject, equipped with an internal search engine, aimed at meeting the information and cognitive needs of academic users.

TracciarisorseOpen has as its priority objective to index digital open access, quality, and accredited resources, belonging to the most varied university disciplines.

The user-friendly interface of TracciarisorseOpen allows not only to select the disciplinary scope but at the same time also the type of resource object of interest (database, EJournals, Ebooks, dictionary etc.) thus allowing the user to identify targeted and personalized search paths aimed at finding trusted resources on the network.

The service is aimed at students, but it is also a valid research tool for teachers, researchers, librarians, the university's technical and administrative staff, and for anyone who wants to carry out research on the net.


TracciarisorseOpen for students: it is a valid tool to find material for the drafting of papers and thesis. The disciplines indexed in TracciarisorseOpen in fact follow the university's educational offer and reflect its complex and consolidated scientific articulation.


TracciarisorseOpen for teachers and researchers: The tool facilitates scientific research by indexing accredited and quality free open access resources.

Resources for measuring and evaluating scientific productivity, resources for patent research and teaching materials for students have also been included.

TracciarisorseOpen for librarians: Provides valuable support for disciplinary reference activity and user orientation.


TracciarisorseOpen for technical and administrative staff: it is a valuable aid for office work. It is in fact possible to find legal sources of quality with free access: regulations, journals, jurisprudence, press agencies, etc.


What's inside TracciarisorseOpen?

Within TracciarisorseOpen it is possible to find indexed digital resources with free access currently selected and carefully evaluated by the Monitoring, analysis and development office of library services and digital reference with the collaboration of University’s librarians.

In selecting resources, priority was given to general disciplinary research tools particularly suitable for academic users: editorial platforms, databases, repositories, digital libraries, online catalogues, dictionaries, encyclopaedias, search engines, portals, sites, social networks, etc.

Thanks to the provision of quality open access scientific resources, TracciarisorseOpen contributes to the promotion of Open Access within the University of Palermo, which in 2004 expressed its support for the international Open Access movement by signing the Messina Declaration in support of open access to scientific literature.


Who's behind TracciarisorseOpen:

TracciarisorseOpen is a project currently coordinated by the Monitoring, analysis and development office of library services and digital reference that inherited it in 2017 from the Digital Library office that had designed the tool and put it into production in 2014 with the aim of promoting the use of electronic resources, both those of the University and open access on the network, to academic users with particular attention to the information needs of students.


Ongoing and future activities

The current presence of the Discovery Tool Service in which all the digital reserved access resources, purchased centrally by the University are indexed, together with open access resources, has led us to make a different choice in relation to the contents to be inserted: we are in fact proceeding gradually to the exclusive insertion of open access resources with characteristics and with paths dedicated to specific categories of users, updated in relation to the current study courses.
