As may be seen on the frontispiece of his works, he was a poor book-seller. He gives the address of his shop: Genshe 23, herring shop, front entrance with a large notice board: “I sell both old and new books and for a good price…. And, I also exchange books.” In the years 1837-1938, Engelsher published twelve booklets in Yisroel-Khayim’s print shop in Bilgoray, each one of them with a sheet of paper bearing the title Der yudisher oytser, a zamlung fun glaykhvertlekh fun ale gedoyle yisroel (Jewish treasury, a collection of aphorisms from all the prominent figures of Israel). On the title page of each booklet, there was a motto and occasionally two or three mottos—a phrase from the Talmud. A new photographed edition was brought out in New York by Yitskhok-Ayzik Shenberger of Brooklyn in the early 1960s, and a new edition also appeared in Israel (Bene-Brak: Yahadut, 1965/1966), 384 pp.
