The Helios repository is an organized infrastructure of digital content, that offers free and unrestricted access to scientific and research material from the National Hellenic Research Foundation.
Scientific results, publications in international journals, research work, conference proceedings, books, training material, sound and image files are available in a fully organized environment, compatible to international standards.
The first stage of Helios' development involves the compilation of all the material provided by the researchers working at the NHRF. New scientific material is continuously being added, while the availability of full text publications is being updated while copyright issues are being resolved.
Feel free to browse the collections of Helios and to search for any specific material in a varied and interesting set of publications offered freely online for the first time on the Internet.
