The Formation of the Jewish Canon

Timothy H. Lim’s The Formation of the Jewish Canon is certainly an interesting book, and Lim explores all the correct sources to try and glean how the Jewish canon came about.  The problem is, this question really has no firm answers, and never will.  The early rabbis expressed reservations about certain books, especially The Song of Songs and Kohelet, and sometimes Esther or Job.  But that is it; the so-called late books were called into question, as we would expect.  How or when the Torah became canon remains a mystery.

There is not much to learn here, unless you are new to the topic.
