He
[Henry James] began dictating directly to the typewriter. It’s a case of the
medium being the message and with dictation he ran into longer sentences, and
parenthetical remarks, and when he revised what he had dictated he tended to
add further flourishes. In the old days when he wrote in longhand he [Henry
James] was much briefer and crisper, but now he luxuriated in fine phrases and
he was exquisitely baroque. It’s a grand style but not to everyone’s taste. —Leon
Edel, “The Art of Biography No. 1” Paris Review interview. 
Not
sure what "dictating into a typewriter means," but I’m trying to write a novel
in longhand. Will my style become briefer and crisper? I’ll have to wait and
see.
I’m
doing the actual writing by longhand, with two of my favorite fountain pens,
both with italic nibs. A Parker Cisele, my first pen, and a Pelikan Souveran 600. I'm keeping my timeline and my bibliography on my computer.
