I recently bought a copy of Trench’s “Synonyms of the New Testament”, which is dated 1901, and is in good shape. I haven’t used it much at all, but it consists of essays on the usage of closely related words. I’m not sure how many books are already on the list, but if this is something that people think would be useful, I’d be willing to help.
I don’t know anything about scanning books or making pdf files, but I could possibly get it photocopied (I’m willing to do the work if I can find a photocopier) or even loan it to Jeff if necessary.
But maybe somebody knows it and can comment first?
