1 K. Zimmermann ftw. Forschungszentrum Telekommunikation Wien PhysDis Electronic Dissertations in Physics The 'European Network for thesis in physics' PhysDis 4 is a collection of available online information and full texts if offered by the author of theses and comes with a search engine for all over Europe online retrieval. The accessed archives differ widely regarding the information offered online. Some offer - only a short entry per thesis like author, title, date - short entry with additional abstract - the online full-text but no metadata - the correct metadata set and the full-text. Add on value like DC metadata helps to improve the retrieval. The distributed search engine Harvest, which we use, consists of 2 parts: Gatherers and Brokers. The Software is 'public domain', a free available, open source code and can be configured to different systems and platforms. An international community fits the software to the latest developments like RDF. PhysDis searches worldwide national libraries / projects / databases. It is devided by subject and linked through Europe: all departments, institutions, computer centers, and digital libraries in the US, too. It is now OAI compliant. According to German law theses have to be published. This can be done by either microfiche, printed copies given to the university and from there to the national library, or an article in a professional journal, or a book by a publisher. In addition, the online distribution is accepted as a publication channel. So the University libraries or the department can act in putting the full text on their web server. The author owns the copyright, independent of who distributes it. Thus (s)he can decide on the channel to be used. A Discussion in DC.Rights concerning the Copyright of the source / document and its metadata is going on. The aim is a copyright note for all databases in the way of (un-)restricted access / use and then quote the national law if necessary. For further information see: 4
