Nope; there's a colon in there separating author from title. Besides, book titles should be italicized; that really can't be changed.
I got two e-mails today, one from a woman who said the bold sort of smooshed together on her screen and stick with the regular, and one from a man who said the regular was anemic and go with the bold.
A compromise may be possible. Since putting letters into bold enlarges them, I tried keeping the bold but dropping back down to size 2 font. I can
read the size 2 when it's in bold, but not as easily as size 3, either regular or bold. But it does get rid of the wiggles in my browsers.
Anyway, if anyone here is not yet sick to death of this whole thing, all three possibilities can now be seen on the same page:
