The book Understanding Jeremiah: Its Setting, Composition, and Message by Duane A. Garrett is currently set as an Old Testament Introduction but is only about the book of Jeremiah.
@Chris Heil We do not have separate categories for introductions to each and every book of the Bible.
An introduction to any Old Testament book will be classified as text.monograph.introduction.old-testament.
An introduction to any New Testament book will be classified as a New Testament introduction.
