“The journal consists of students’ notes from R. Joseph B. Soloveitchik’s Talmudic lectures and original essays on halakhic topics related to the kosher laws.”
Just to be clear,the notes from RYBS lectures are not limited to issues of kashrus — they are wide ranging over the entirety of Shas. In addition, the journals include halakhic essays from contemporary poskim specifically in the area of kashrus.
