Except in the case of American works, which might easily have escaped Marie Manacéïne’s attention, I have not tried to go further back than that Bibliography, as she was most industrious in research; I have only cut out from her list what seemed the more obsolete or needless works. But with the help of A. T. Craig and others, I have carried it, as far as may be, down to date. Bibliography Selected from that Given in “Sleep” (Manacéïne).
