The paper examines the sentential and quantificational forms of distribution in classical, intuitionistic and relevant logics, and in relation to quantum mechanics. Particular attention is also paid to the first author's logic MCQ of meaning containment. The ultimate aim is to determine whether distribution should be included and, if so, in what forms. We conclude that the sentential and existential rule-forms, both derivable from the two-premise meta-rules of MCQ, are the only two forms that generally hold.
