9Based on the extremely popular Koren Sacks Siddur, the Koren Shalem Siddur is a new, enhanced siddur that includes the entire contents of the Sacks Siddur and:

- All Torah readings with new translations for the Shalosh Regalim and Hol HaMoed, Hanukka, Purim, Yom Ha'atzmaut and Yom Yerushalayim

- Modern English translations of the Five Megillot

- Additional personal supplications (tehinot)

For ease of use, and to facilitate adoption in synagogues and schools, the Koren Shalem Siddur maintains the same pagination as the Koren Sacks Siddur.
