The "Mishna Berura", the main work of "halakha" by Rabbi Yisrael Meir Kagan (the ""Chafetz Chaim"") is a collation of the opinions of later authorities on the "Orach Chayim" section of the "Shulchan Aruch". "Aruch HaShulchan", by Rabbi Yechiel Michel Epstein, is a more analytical work attempting the same task from a different angle, and covering all sections of the "Shulchan Aruch". The former, though narrower in scope, enjoys much wider popularity and is considered authoritative by many adherents of Orthodox Judaism, especially among those typically associated with Ashkenazic "yeshivas". The "Ben Ish Chai", "Kaf Ha'Chaim", and much more recently, the Yalkut Yosef are similar works by Sephardic Rabbis for their communities.
