Q. Can one get undressed or have marital relations in a room were seforim or English Torah magazine articles are kept in a closed night-table drawer?

A. Horav Shlomo Miller’s Shlit’a opinion is that the seforim or magazines that contain proper Torah articles should be covered even when inside a closed drawer.
If the night-table or night-stand are large and the drawer is more than four tefachim by four tefachim (about 40 cm. square), and the unit is also ten tefachim high (80 ”“ 100 cm.) the Rov maintains that the seforim inside do not have to be doubly covered, since they are already in a separate domain. However, most night tables lack that height, therefore the seforim and divrei kedusha inside require an additional cover.
