There's a lot of x-phi stuff by Knobe and friends available online - mostly about all the same sorts of topics at the moment. There's also a book called "Experimental Philosophy" edited by Knobe and Nichols... not quite a textbook, more a collection of papers with insufficient attention to detail on methodology... nonetheless, it's a pretty good book for those interested in the field.

Doris doesn't seem to host his stuff online, but here is a good starting place for interest in the field (hosted by Knobe).
