Authorised Daily Prayer Book

[2] Singer's goal was "to unite accuracy and even literalness with due regard to English idiom, and to the simplicity of style and diction which befits the language of prayer".

[3] The siddur became popular not only due to the quality of its translation, and its relatively compact size, but also because the Montefiore family paid for its production, allowing it to be sold for one shilling.

The siddur was expanded in 1917 under Chief Rabbi Joseph Hertz; 1934 saw a "continuous" version, minimizing the need for cross-reference, and which also incorporated additional material.

The 1962 Second Edition, under Chief Rabbi Israel Brodie, was completely re-typeset; also the translation was amended where it had become unclear or archaic, and further additional material had been introduced.

[4] The latest edition of the Authorised Daily Prayer Book - aka the New Singer's Siddur was published in June 2023, by the current Chief Rabbi Sir Ephraim Yitzchak Mirvis KBE.
