Some first thoughts about this Logos edition. I own the 2nd german ed. with Schall's Appendix in print (1966) (I'd love to have this in Logos, but I'm not dreaming, that there are enough people wanting that to produce it.) Based on the description of the Logos edition one will think to only buy the english translation of the 2nd ed. In fact there is also a translation of Schall's appendix (which are Nöldeke's handwritten notes in his own copy.) That's great, BUT what is missing is a link (or at least some sign) that there is a note (addition or correction.) In my printed copy there are bold numbers in the margin, the english translations says to give F plus page number of the appendix. I didn't found that in the main text. It would be great, if there was a link to hover over (like a footnote) and read the note. In the present form the only use case I am aware of, is that the text of the appendix is searchable and may give an unexpected result, if you e.g. search "all books". P.S. I hope such linking gets done for all "corrigenda", at least in grammars and lexicons
