It's helpful to remember that there is the Fortress Commentary (in 2 volumes) and then the Fortress Commentary Study Guides. You will find links to both below!
The Fortress Press Commentary on the Bible (2 volumes - Old and New Testament) are shelved in the Reference Room on Level 2. Those copies do not circulate and are in-library use only. If you need to use this resource from home, consider using the Study Editions (ebook format) found on this page.
