These are piyyutim written in a traditional style, meant to introduce the opening of each book in the Torah. These piyyutim can be used at any time the opening line of the reading is said – on the Shabbat Minḥa/Monday/Thursday prior to the reading OR on the Shabbat morning of the reading proper. Because of this, the sheets arranged including the readings use two sizes – a larger size for the shorter first reading for weekdays, and a smaller size for the full first reading on Shabbatot. They can only be read when the first verse of the book is read.
