The number one thing my reading is inspired by is my mood. There are times when just can't decide what to read next. I have books everywhere, and they all looked interesting to me at one time or another, but what I pick next is definitely inspired by my mood. Do I want something quick and fun, or something takes a involves a little more thinking? Fiction or non-fiction?
My reading (or at least my acquisition of books) has also been inspired by certain subjects. Once a subject catches my attention I tend to be a bit single minded in finding more about whatever it is. For example, I find all things Russian fascinating and have tons of fiction and non-fiction, in lots of different time periods, set there. I don't know when I will get them all read, but they are at my fingertips when I feel so inclined.
