The first book from Bass's press appeared in the middle of August, 1689, the first customer being, as he had anticipated, a Polish scholar, Rabbi Samuel ben Uri of Waydyslav, whose commentary "Beit Shmuel" on "Shulchen Aruch", "Even Ha'ezer ", was printed at Dyhernfurth. The books that followed during the next year were either works of Polish scholars or liturgical collections intended for the use of Polish Jews. Being issued in a correct, neat, and pleasing form, they easily found buyers, especially at the fairs of Breslau, where Bass himself sold his books.
