5. Responsa, by Rabbi Yoel Sirkis author of Bayit Chadash - Bach responsa. Frankfurt am Main, [1697]. First edition. Lacking [2] leaves at the end of the book. Ownership inscriptions.
6. Ma'amar Mordechai responsa, Part 1, by Rabbi Mordechai Halberstadt. Brno, 1790. After it was published, this book was archived and banned and is especially scarce. Already in the 1860s, the author of Nachal Eshkol wrote (Sefer HaEshkol, Part 2, p. 187, Brit Avraham p. 24) that the book was non-extant and he has only seen one copy. He attributes this to the fact that the Frankfurt sages burned the book following the printing of a responsum by the Pnei Yehoshua (Siman 56) regarding a dispute about "tumat ohel" in the main street of the Frankfurt Jewish quarter. Dedication on title page.
Six books. Size and condition vary.
