We are glad to announce that Matenadaran has signed an agreement of collaboration with the Belgian publishing house Brepols (founded in 1795), one of the internationally known publishers specialized in medieval studies. Brepols, widely recognized for such authoritative book series as Corpus Christianorum, Patrologia Orientalis, Corpus Christianorum Series Apocryphorum and others, will publish our new international academic journal MEMAS (Matenadaran: Medieval and Early Modern Armenian Studies). The journal is biannual (two issues per year), it will be published online in open access and also printed at the end of each year. The presentation of MEMAS will take place on July 22, in Tatev, during the International Armenological Congress.
