If I pick a book of the shelf because the topic is generally of interest to me my usual purpose is..."Is there anything new to me in this book, anything I don't already know. Is this authors view on this different in any way that I'm aware of?"
Afterall you don't really want to re-read the same book over and over again if you're looking for new ideas on the subject?
In this case I still activate the book with at least one activation pass. If it is that interesting that I consider it worthy of a closer read I move to rapid read. This is proving rare even on books that interest me though.
Either way I would always photoread it first. It's fascinates me how often I feel that there is nothing new in the book after photoreading it only to confirm it during a post view. This saves me a lot of time for other books.
