Rod Decker just made me aware that the older, public domain, ICC volumes are available online. This includes the volume on Galatians by Ernest De Witt Burton published in 1921. Several formats are available but Decker recommends the pdf page scans. I immedaitly grabbed Galatians. The download was fast and the page scans are very crisp and clear. This is very good work!
Google Reader just popped up with another blogger who was inspired by Decker and posted a list of OT commentaries available as well. Check out his post here.
