My OCD bookish habits -
(Do you religiously bookmark your books?
Refuse to read more than one book at a time?)
Not knowing how to pronounce a name or city or not being 100% certain of a word's definition will have me snatching up my dictionary or running to my computer and pulling up Google. It disrupts the flow of the story, but I can't continue until I'm satisfied that I'm reading everything correctly. Of course, that doesn't always work out because sometimes the authors have created completely original worlds and there are no references to help me with some of the names they come up with, but I can't go back to the story until I've at least given it a try. What about you? Do you have any OCD habits when it comes to reading?
