My Simpson/Day edition dates from 1986. ....... I wonder whether newer editions still have only numbers? ......
Just found the answer to my own question. NHBS shows a few sample pages on their fine website. Thus, the names are now on the plate page as well. Certainly an important improvement over my old edition. Also, some of the pages look basically unchanged whereas others look redone. There are limits for comparing as the samples are not very large. Sufficient to give a good overall impression though.
