# 18.2 Prohibition on combined category documents.

(a) The Director of the Federal Register will not accept a document for filing and publication if it combines material that must appear under more than one category in the *Federal Register.* For example, a document may not contain both rulemaking and notice of proposed rulemaking material.

(b) Where two related documents are to be published in the same *Federal Register* issue, the agency may insert a cross-reference in each document.

[54 FR 9680, Mar. 7, 1989]
