Keil

As a follow up to noting Rob Bradshaw’s additions of Charles Simeon and John Lightfoot’s works in conveniently accessible PDF files, some other possibly helpful resources across which I’ve recently stumbled (sometimes apparently afresh) include: Keil and Delitzsch’s Old Testament commentary via Internet Archive; Various helpful texts via University of Pennsylvania’s Online Books Page; and The overall, searchable list of “Hosted Articles, Monographs, and Books” at BiblicalStudies.org.
