Hmm let's see:
When I go somewhere (ie. to visit family or to the university), I usually bring a book.
I use a bookmark, which one depends on what kind of book it is (I have certain book marks for certain types of books), or which one has my preference, which one I just bought etc. I do have a lot of bookmarks, they're a nice little collection (most of them were free from the library when I was a child).
I read books in English or Dutch.
I'm quite a fast reader.
I don't like audio books, because of the way hearing works with my brain.
I try not to read more than one book at a time, because this gets confusing. I had to read several books at a time for school (ie. for Dutch, English and at home) and it was always confusing.
I try not to read too many series at once, for the same reason as above. Unfortunately this can't always be avoided as I have to wait for the whole series to be published etc (and I'm not always that patient

). so I'm usually reading several series at once.
I can't read a series out of order either, it doesn't seem right.
I try to keep my book shelves not messy and put the books straight etc. But because I have quite a few books, it does look a bit messy as I kind of need more space, for it to be less messy.
I never read while walking, I can't do that.
I sometimes read in the train, I can't read in a bus and not too keen on reading in a car. I can get carsick. I used to read a lot in cars though until I developed my carsickness. I normally don't read in a plane, because it's awkward to get to your bag etc (I can't reach the compartment above people's heads easily and I try to always sit by the window).
I try to see what other commuters are reading.
I never read in a bath, nor while cooking. I can't do too many things at once. I do sometimes read when the computer is starting up.
I like silence when I read, however on the train I use my iPod so I can read while listening to music. It's really hard for me to read (or concentrate on anything) when it's noisy.
I prefer to read in my room, sitting in my chair in front of the computer.
I sometimes reread books, however most of the time I'm reading new books.
I don't read aloud.
I used to have a real problem with first person books when I was a child, thinking it was about me. Nowadays I can read them without trouble.
I never make folds in the pages of a book.
I love the smell of new books.
I'm pretty proud of my book collection, my books mean a lot to me.
I buy books pretty much all the time

.
I usually buy more than one book at a time.
I prefer to own books rather than borrow.
I often buy a book, then look forward to it so much I don't read it until some time later on. The 'looking forward to reading it' can be a lot of fun!
