Putting a tallit on top of a siddur or other sacred book

Hi,

One may not put a tallit on top of a sacred book, like a siddur; its own sanctity is of a lesser degree. However, one may do this for the protection of the siddur, or for its honour. Therefore, one may wrap a Torah scroll with a tallit to preserve its honour or safety.

(Rivivot Ephraim 1:119:1)
