Comment on arXiv:1810.04634v1 [cond-mat.str-el], "Hole-pocket-driven superconductivity and its universal features in the electron-doped cuprates"

The following letter, titled "Electron-Superconductivity in Oxides?", was submitted to Nature [Scientific Correspondence Section] on March 2, 1989, shortly after the experimental discovery of electron-doped cuprates announced in Nature on January 26, 1989. It predicted the findings recently reported in arXiv:1810.04634 by Yangmu Li, W. Tabis, Y. Tang, G. Yu, J. Jaroszynski, N. Barisic and M. Greven that "clearly point to hole-pocket-driven superconductivity in these nominally electron-doped materials", "reveal hole superconductivity in the electron-doped high-temperature superconductors" "after three decades of enormous scientific inquiry", and point to "a single underlying hole-related mechanism of superconductivity in the cuprates regardless of nominal carrier type". Many more papers on this topic were published by F. Marsiglio and the author in the ensuing 30 years from 1989 to the present. In omitting to refer to any of these theoretical works, arXiv:1810.04634 presents a misleading picture.
