““Codex Leningradensis B 19a, used by R. Kittel and P.E. Kahle as the basis for the third edition of Biblia Hebraica and for the edition by A. Dotan. It has been corrected by a second hand, responsible for many erasures and changes in order to make the text conform more closely to bA, although it still preserves some bN readings. Its colophon bears the date 1008/09, and according to the scribe it was a copy of a manuscript vocalized by Aaron Ben-Asher, who also provided the masorah. It is the manuscript which approximates most closely to the Aleppo Codex, although it differs occasionally in vocalization and accents. Its masorah is later and sometimes contradicts the text.””
