Tommy Wasserman points to an important resource:
Emanuel Tov has graciously made available a large number of his publications on his website here, including his two volumes on Scribal Practices and Approaches Reflected in the Judean Desert.
Congratulations!
Those interested in OT Text Criticism will want to access this material.
What would be some of his most important works given on this site?
Definitely get the scribal habits ones.
