On the prepub "Biblical Languages:Reference Grammars and Introductions
(19 Vols)" there is a classic Greek grammar by Herbert Smyth called "A
Greek Grammar for Colleges" that was published in 1920. The problem is
the grammar that is referenced by so many others is the 1956 revised
edition of that grammar.
The description only says 1920. If so, would they consider replacing
that version with the 1956? The issue they may have is anything before
1923 does not have copy protection. The version everybody references
still has copy protection which would mean a license fee.
