- Mishna Berura ("Clarified teachings") is an important and widely used commentary, consisting of six volumes, on the Orach Chayim section ofYosef Karo's digested compilation of practical Jewish Law, the Shulchan Aruch. It combines his own elucidations and differing opinions with those of other Aharonim (post-medieval authorities.) [As found in the book by Rabbi Moses M. Yoshor "The Chafetz Chaim" on page 603 the 1st volume was published in 1884; 2nd volume in 1886; 3rd volume in 1891; 4th volume in 1898; 5th volume in 1902; 6th volume in 1907.]
- Biur Halacha ("Explanation of the Law") is a commentary tangential to the Mishna Berurah. It usually provides complex analysis of the legal rulings of earlier Jewish halachic authorities.
- Sha'ar HaTziyyun ("Gate of Distinction") serves primarily to document sources for laws and customs quoted in the Mishnah Berurah, but sometimes serves also to clarify ambiguous legal statements. The name Sha'ar HaTziyyun derives from the phrase sh'arim m'tzuyanim ba'halacha, translated as "gateways distinguished in (or marked in) Jewish Law," referring to the Torah study and scholarship that would distinguish Jewish homes. Rabbi Kagan chose the title as a pun, hinting at the distinction of the scholarship referenced in his work, but primarily referring to (as he writes on his title page) the function of Sha'ar HaTziyyun to document (mark) sources.

- Tzipita L'Yeshuah ("Have you yearned the redemption") is based on a passage from Tractate Shabbat, which states that after one passes away, he is asked by the heavenly court: "Have you yearned for the redemption?" This work describes the importance of actively awaiting Moshiach every day and doing everything in our power (learning Torah and doing mitzvot) to bring the redemption. The Chofetz Chaim's expectation of the immediate redemption was so strong that he would always carry special garments to change into once the redemption begins.
