Shneur Zalman of Liadi. (Tanya) - Likutei Amarim.

the first tanya printed in america. this copy with mauscript corrections in the hand of the late lubavitcher rebbe, menachem mendel schneerson. Although the Vilna edition has remained the standard layout for all subsequent editons of the Tanya, in preparation for the publication of the first American edition in 1953, the Lubavitcher Rebbe, Menachem Mendel Schneerson, noted that a number of minor corrections were needed. Using this printer's proof, the Rebbe indicated in pencil a handful of errors. This copy was then forwarded to the printer to be used as a matrix for the printing of the tens of thousands of subsequent editions published all over the world for decades hence. Accompanying this lot is a description specifying the importance of this work, along with a letter written by R. Chaim Shaul Bruk, editor of Hanachoth BeLashon HaKodesh, attesting as to which pencilled corrections are in the hand of the Rebbe. It has been further suggested that additional corrections are in the hand of the Rebbe. Clearly, further research is required.
