Analysis of information sources in references of the Wikipedia article "Tisha B'Av" in English language version.
Tisha b'Av is forbidden for washing, anointing, wearing leather shoes, and marital relations. It is also forbidden to read from the Torah, Nevi'im, and Ksuvim and to learn mishna and midrash and gemara and halacha and aggada, because it says, "The precepts of God are right, gladdening the heart" (Tehillim 19:9). Schoolchildren are idle on it. One may read Iyov and the bad things which are in Yirmiyah, but if there are between them passages of consolation, one must skip them.
