The Nehora HaShalem siddur is a prominent siddur, comprising commentaries, selections and kavanot, with essays on the importance of prayer and more. The authors and compilers are R. Yechiel Michel son of R. Akatriel HaLevy and his son R. Aharon HaLevy of Mikhalishok. The siddur was widely accepted, and received approbations by prominent Torah leaders, including Chassidic leaders. It was therefore printed in several places, including Berditchev and Slavita. The editor, R. Aharon HaLevy, later sold the rights to this siddur to the printer R. Menachem Mann son of R. Baruch of Vilna (see the sale contract printed in the Avodat HaLev edition of Siddur Nehora, Vilna and Horodna, 1819).
This edition was proofread by R. Tzemach Segal Landau of Vilna, who added his commentary Iyun Tefillah. The siddur includes many additions, including: Tikkunei Shabbat, Passover Haggadah with commentaries, and the priestly blessing (on final two leaves).

[21], 2-315, 9, [3] leaves. 17.5 cm. Mostly printed on fine, light-colored greenish paper. Good condition. Stains, including large dark stains to some leaves. New leather binding (incorporating parts of original leather binding).

Rivkind maintains that the siddur was printed in Aziory, a town near Horodna, where the press of the partners from Vilna and Horodna operated for some time. Yaari however rejects his claim. See: Y.
