The decade from 1887 to 1897 saw the appearance of Mandyczewski's work on the Schubert Gesamtausgabe. His name is particularly associated with the ten volumes of songs, which he edited meticulously, sometimes printing as many as three or four variants of individual songs; in recognition of his editorship he was awarded an honorary doctorate from the University of Leipzig in 1897. A gifted philologist as well as musician, he was widely respected both for his scholarship and for his generosity to inquiring scholars; Grove was indebted to him for his help in the writing of his book on Beethoven's symphonies. Mandyczewski also brought out a second volume of Nottebohm’s "Beethoveniana", a series of pioneering essays in Beethoven scholarship that had been partly published in series in the "Musikalisches Wochenblatt" and partly left in manuscript.
