Interesting to see a new book on this, but disappointing that it seems to re-tread much of what was already known of the author --- maybe this is going to be a trend/standard for future writing about authors and their works for this window of time where folks still wrote letters? It is now possible to exhaustively analyze such correspondence far more easily than the laborious manual pouring over of photocopies and archives (for Mann, apparently, in addition to Yale, Baylor, Princeton, and the University of Bonn and the Library of Congress hold extensive collections).

Makes one wonder what will happen with recent and contemporary authors --- will their e-mail correspondence survive to be preserved? I know I've lost access to two major sets of my e-mails from previous employers and will lose access to the current one at my retirement (unless I go back as an annuitant? Copy the Outlook .pst archive?) --- at one point in time, Barry Hughart's (typewritten!) notes for his books were available on-line, but they have since vanished....

Interesting, and I'll have to add it to my to-be-read stack --- wondering if Hesse will get the same treatment (or already has and I missed it?) --- his _The Glass Bead Game_ was quite influential on me and probably is why I'm fascinated by software tools such as OpenSCAD Graph Editor.
