Book excerpt: Throughout the generations, the Siddur underwent significant changes and alterations, until the result was sometimes confusing and rife with errors. Rav Yaakov Emden (the Ya'avetz) sought to change this by painstakingly creating a Siddur with carefully chosen text, with laws and instructions to enlighten the person praying from it, and with the finest typography and paper he could procure. His Siddur, first published over a hundred years ago, was met with widespread acceptance. Now this monumental work has been translated into English, adding an extra dimension of meaning to all who find translation helpful. While the primary value of the original Siddur is as a reference work, the translated Siddur was intended to be used as an actual prayerbook. To that end, the Siddur was produced in two volumes: one contains all the introductory and explanatory material, replete with laws, Perek Shirah, and appendices, and the second volume contains the morning service with Rav Emden's instructions, notes, and commentary along with some additions. With clear, easy-to-read print, this is a Siddur truly in a class of its own. Nusach Sefard. 2-volume, shrink-wrapped set.
