12 volumes (out of total 26). 12 volumes in full detail, probably archived, meta-info’ed, DOI’d.
May seem easy. Not really. It took lots of effort and time to complete digitizing the first 12, most recent proceedings volumes of the Annual Symposium of the Hellenic Nuclear Physics. The series is titled “HNPS Advances in Nuclear Physics” and is hosted on the National Documentation Center servers under a mutual MoU.

And if you are a fellow researcher, join us in the next Symposium of our Society. May 2020 in Athens. Another fun 2-day Conference, another volume with interesting research works.
