In Volozhin, they learned the entire Tanakh with Rashi and Moses Mendelssohn’s biur; all sedros of the Mishnah, except Taharos, with “biur” (could most likely be Bartenura), Shulchan Aruch, Dikduk, and Berakhos, Shabbos, Pesachim and Eiruvin, Chulin, Niddah, Yevamos, Kesuvos, Gitin, Qiddushin with Rosh (Rashi, Tosafot also, perhaps).
