While there is much discussion regarding the fidelity of the transmission of the NT text, very little attention is given to the OT.  I’ve long been looking for a good book dedicated to OT textual criticism, written from the perspective of a conservative text critic, so I was happy to come across John F. Brug’s Textual Criticism of the Old Testament

Brug does a great job of explaining the manuscript resources, how text critics go about establishing the original text, ancient and modern criticism of the text, and many examples of the variants with a fair assessment of which are original.  What I was particularly interested in is his explanation of the differences between the Greek translation and the Hebrew, as well as the differences in names and numbers in parallel passages such as Kings and Chronicles.

The book is under 200 pages, so it’s very digestible.  I would highly recommend this as an intermediate introduction to OT textual criticism.
