The present volume opens a new series of publications of our Museum: The Heritage Series, presenting only the first part of the Bulgarian lot, for the moment; the second part of the same will document the coins and ponds it alsa includes. At the same time, the already existing collections, such as the Fire Arms and Knuckles Collection and the Prehistorical Metal Items Collection will be published, alongside the new acquisitions or "thesauri" of this sort, which have now been brought to light for the benefit us all.
