Ibson Beckwith’s substantial [794 page] introduction and commentary on the book of Revelation has been reprinted numerous times since it was first published in 1919, indicating that its content is still useful.
I have scanned the book and converted it to PDF so that it can be accessed more easily – this version is 15MB – far smaller than the 48MB version on archive.org.
