The Forthcoming Books page (and the Publication Month search page) can show magazine pubs as reprints if the corresponding EDITOR record uses the YYYY-MM-00 rather than YYYY-00-00 format. Since magazines can't be reprints and since EDITOR records are sometimes assigned months in order to ensure that they are sorted properly, the logic should be changed not display the word REPRINT for magazines.
