2 CFR § 200.461 - Publication and printing costs.
(a) Publication costs for electronic and print media, including distribution, promotion, and general handling are allowable. If these costs are not identifiable with a particular cost objective, they should be allocated as indirect costs to all benefiting activities of the non-Federal entity.
(b) Page charges for professional journal publications are allowable where:
(1) The publications report work supported by the Federal Government; and
(2) The charges are levied impartially on all items published by the journal, whether or not under a Federal award.
(3) The non-Federal entity may charge the Federal award during closeout for the costs of publication or sharing of research results if the costs are not incurred during the period of performance of the Federal award. If charged to the award, these costs must be charged to the final budget period of the award, unless otherwise specified by the Federal awarding agency.
