Visited a used book store. They had a reasonably nice hardback of A Manual Grammar of the Greek New Testament Dana and Mantey 1957. Had a nice foldout chart of some sort in it.
Searched for it here on the site but found very little.
The book looked intriguing though perhaps a bit over my head. Is it something that Logos should add? Is it superseded by something newer? Would I do well to pick up the used copy?
