The Haggadah was published using photocopying equipment and distributed in hundreds of copies across Moscow and other major cities of the former Soviet Union. This Hagadah was meant to instruct in leading an exciting and spiritual Seder. In Israel Polonsky together with Machanaim published: a Siddur (prayer book) with a Russian translation and commentaries titled "Vrata Molitvy" (Gates of Prayer, not to be confused with the Reform "Gates of Prayer, the New Union Prayer Book"). Until this day it remains the most widely used prayer book in Russian; a transliterated edition is also available); Machzor "Gates of Repentance" for Rosh Hashanah and Yom Kippur; Passover Haggadah with commentaries; a book titled "Obligations of the Living", on the Laws of Mourning, as well as a series of books about Jewish holiday customs and observance. Research of Rav Kook's legacy In 1991 Polonsky partnered with Rav Kook's Home Residence Museum in Jerusalem and prepared the publishing of a compilation of Rav Kook's works titled "Tolerance in the Teaching of R. Kook". During the course of his research of Rav Kook's philosophy and body of work, he wrote and published a study (monograph) titled "Rav Abraham Isaac Kook. Life and Teaching". In 2009 the main chapters of the book were translated and published in English, and in 2013 into Hebrew. It became the first book on Jewish religious thought translated from Russian to Hebrew. The book was approved by several major rabbinical authorities on the subject of Rav Kook's philosophy and was recommended by them to be included in the Religious Zionist academic curriculum. Torah commentaries "Bible Dynamics" A series of books presenting a new commentary to the Torah, based on the Kabbalistic concepts of R. I. L. Ashkenazi (Manitou) and on new findings of R. Uri Sherki, which included the author's own original concepts and interpretations. As of March 2020, a full commentary on the Torah (11 books) have been published. An English translation of Genesis, Part A, "Be Reshit - Chayei Sarah" has been published in the fall of 2019. The first part of Genesis in Ukrainian has been published in 2019 as well. Other works In 2009 Polonsky - among others - became one of the founders of an Academic wiki-encyclopedia on Jewish and Israeli topics. The goal of the project is the publication of a complementary (to Wikipedia and other sources), academically viable information on Judaism, Jews and Israel
