Wired magazine has a short article on E-Book design — the first I’ve read that is focused on the design of the digital texts themselves, not the hardware. The article cites cover designer Henry Sene Yee and typeface designer Mark Simonson for input.
“Different typefaces are like like having different actors in play or different voices in an audio book,” Simonson says. “The variations in typeface influence the personality of the book. Sticking to one font is much like having the same actor play all the different parts.”
Licensing embedded fonts for e-books appears to be a unique and lucrative opportunity for typographers, I hope these guys are paying attention.
