What is the place of Friedrich Neue’s and Carl Wagener’s Formenlehre der lateinischen Sprache (1892—1905) these days? Is it still used and can it still be cited, or has it been replaced by, um, something? I have been using Manu Leumann’s Lateinische Laut- und Formenlehre (1977), but evidently the dimensions differ a lot.
I used N—W for the first time only a few days ago, as I checked a reference in ThLL s.v. pī(n)so (this lemma is from 2003).
