Zhagorski, Yankev
He was a collector of published Yiddish works in Latvia. In his home in Riga, he had numerous published Yiddish rarities. He also compiled an assortment of bibliographic listings—unfortunately, few of them were published.
In YIVO-Bleter (YIVO Monthly Bulletin) (Vilna) 4 (1932), pp. 88-89, there is a bibliographic list he prepared of the Latsky-Bertoldi’s articles in Fraynd (Friend) in St. Petersburg.
What happened to him in the period of WWII remains unknown.
