Does Language consider papers for review whose (partial) findings or whose very short version has been published in conference proceedings?
Our policy is to regard everything except for working papers as prior publication. If some of the results in a submitted paper have been published elsewhere, the paper you submit should build on those results and should develop the ideas and evidence along new lines or in greater depth. In cases where you are not sure if the degree of overlap is too great, please send the previous publication along with your submission; the need for such a step should be rather rare, though, in practice.
