I got asked to write a small article for a non-peer-reviewed journal and was pretty excited about it. However some of the faculty at my institution referred to it as a "throwaway journal." What does this mean? At first I thought it referred to something you throw away without even looking at (i.e. not very important or reputed), but my friend said it simply meant something that isn't peer-reviewed and doesn't cost money to subscribe. So what is it?
