This doesn't say "rev ed" but it is the revised edition:
https://www.logos.com/product/49143/the-supremacy-of-god-in-preaching
This says "rev ed" but it is the original:
https://www.logos.com/product/5356/the-supremacy-of-god-in-preaching-rev-ed
Thanks for pointing this out. However, that's not quite accurate.
1990: original edition
2004: revised edition
2015: revised and expanded edition
So https://www.logos.com/product/5356/the-supremacy-of-god-in-preaching-rev-ed is correct, but https://www.logos.com/product/49143/the-supremacy-of-god-in-preaching needs to be revised, er, updated.
I'll have the team update it.
