These titles, formerly published by Twayne in hardcover, all seem to be about literature or literary criticism, so it's likely the L- prefix refers to Literature. College & University Press began publishing softcover editions of Twayne's titles starting in 1962 (see College and University Press Publishes First Books, PW, Mar. 12 1962, at 37).
