I'm looking for a list of journals in the field of literature that provides information on submission and publication rate.
I believe you're referring to the MLA Directory of Periodicals, which is now incorporated into the MLA database.
Go to the MLA International Bibliography database (under M on the Library's DATABASES tab). Then in the blue bar at the top, you'll see MLA Directory of Periodicals. You can enter a publication name or browse alphabetically. Each journal's entry will include whatever information the publication submitted to MLA.
