After finishing his studies, Slatkine returned to Rostov-on-Don and started a marine insurance business. In 1903, he published his first article on Hebrew bibliography in the Russian-Jewish daily newspaper
HaMelitz. In 1905, he moved to
Geneva,
Switzerland, fleeing
pogroms. There he opened a bookstore and, later, a publishing house which operates to this day under the name
Slatkine and is owned by his descendants. While living in Geneva, he continued his bibliographical research and wrote several books, including
Shemot ha-Sefarim ha-Ivrim on titles of Hebrew books and
Bikkurei ha-Bibliografyah ba-Safrut ha-Ivrit on
Shabbethai Bass, the first Hebrew bibliographer. He also published
Mi-Sefer ha-Zikhronot shel Rav Litai, featuring "selected chapters" from the "memoirs" of Lithuanian rabbis, which some believe to be a mystification entirely written by Slatkine himself. ==Family==
