Beit Aharon, on Torah and service of G-d, by Rebbe Aharon Perlow of Karlin. Brody: Moses Leib Harmelin, 1875. First edition.
The book begins with a collection of Azharot Kodesh, and records of Chassidic practices from the rebbes of the Karlin-Stolin dynasty: R. Aharon HaGadol of Karlin, his son R. Asher (the first), the latter's son R. Aharon (the second), and his son R. Asher (the second).
The renowned Shabbat song – Yah Echsof Noam Shabbat by R. Aharon HaGadol of Karlin is printed on leaf 6 (p. 11). The foreword explains that this book was named Beit Aharon, since that was how R. Aharon (the second) of Karlin would refer to his writings, in reminiscence of the way his grandfather R. Aharon HaGadol, when his son R. Asher once inquired at the age of 10 as to the source of the song Yah Echsof, replied "Beit Aharon" (the house of Aharon).

Some corrections were made to this first edition during the course of the printing, resulting in variations between the different copies.

In some copies, this passage was printed in a different location, with textual variations (see R. A. Shor, "Regarding the Writing and Printing Process of Beit Aharon", Beit Aharon VeYisrael, VI, 1 (31), pp. 139-147, regarding the stages of printing of this book, and the corrections made during the course of the printing, resulting in differences between the various copies).
