has gone through many large editions and which has probably been the most popular (both with Jews and Christians) of any book published by an English Jew. The Hebrew text was that of Seligman Baer's classic Avodat Yisrael, to which Singer provided an "authorised" version of the liturgy capable of standardising and stabilising the synagogue service and helping to create an "established" Judaism in Britain and the Commonwealth (the so-called "Minhag Anglia".) The Siddur was expanded in 1917 under Chief Rabbi Joseph Hertz; 1934 saw a "continuous" version, minimising 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. The Centenary Edition of 1990 saw an extensively revised translation by Rabbi Eli Cashdan, and also included a series of explanatory notes by Chief Rabbi Lord Jakobovits. In 2006, Chief Rabbi Jonathan Sacks penned a new translation, with commentary, instructions, laws & rubrics; this Fourth Edition formed the basis for the Koren Sacks Siddur published 2009. This Siddur – in its various editions – has remained the standard prayer book for most orthodox Jews in Great Britain, and for many in the Commonwealth, and is still informally known as the "Singer's Siddur." In 1915 the Bloch Publishing Company published an American version, The Standard Prayer Book, which was widely used until the introduction of Philip Birnbaum's Ha-Siddur Ha-Shalem in 1949. In 1896 the Cambridge University Press published Talmudical Fragments in the Bodleian Library of which Singer was joint author with Solomon Schechter. Israel Abrahams had access to all of his manuscripts and, after Singer's death, produced three volumes of his literary remains (1908). In 1914, Abrahams also published an annotated edition of Singer's Siddur, with "Historical and Explanatory Notes".
