Perhaps some of the following will spark some more ideas:
Victoria Regina Tarot. Do an online reading. Some people find such things helpful in generating a plot. I used the tarot as a plot device in my first Nano novel.
Unusual Life. Lots of weird buildings and other assorted stuff.
What Ails the Short Story. An NYT piece by Stephen King on the current state of the short story. I'm primarily a short story writer and I sort of find it paradoxical that one way into publishing is to build up a short story career first--even though the market for short stories have been steadily declining.
Mrs Beeton's Book of Household Management. If you're writing anything in the Victorian age, this might be helpful. It would have been helpful to me had I seen this before I was writing my steampunk-based Nano novel in 2005.
It Just Got Easier To Be A Bestseller. Bah. I never pay attention to those book lists anyway. They could slap on "#1 Bestseller!!!" on every book and I would still not pay attention. The only way I'm going to buy a book is if the story looks interesting.
