Use these directories to identify periodicals (scholarly journals, industry, and mainstream magazines) and book publishers by their subject or genre focus.
MLA Directory of Periodicals (part of the MLA International Bibliography--click on "Browse Periodicals" at the top of the search screen to get to the directory): Major directory of periodicals in literature, rhetoric, language studies, film, and drama which includes contact information, subject scope, submission requirements, circulation numbers, and often acceptance rates.
Ulrichsweb: A directory of over 160,000 magazines and journals; use the Advanced Search to limit to scholarly/academic journals. The subject categories are very broad, i.e., "Education" so try a title search if the subject search isn't retrieving what you need. Major titles usually have a yellow star next to them and often link to reviews from Magazines for Libraries or Library Journal.
