This release is a reformatting of Project Gutenberg's version of Dracula. And as such inherits the lack of italics in various portions of the text.
Stoker uses italics to provide emphasis and nuance to his characters' thoughts. Unfortunately PG tend to discount the typographic necessity of italics and this release suffers for that lack of sensitivity.
The only no-cost version of Dracula that I have found that does include italics is Barnes and Nobles's classic series.
My rating indicates my dislike for merely tarting-up and copying a poorly presented edition.
