s 230 Publication — publishing unpublished old authorial works in public collections
230.—(1) It is a permitted use of an authorial work (called in this section the old work) to publish another authorial work (called in this section the new work) that includes the old work (or any part of the old work) if —(a) immediately before the new work is first published —(i) the old work is unpublished old material in a public collection; and (ii) the publisher of the new work does not know who owns the copyright in the old work; and (b) before the new work is first published, the prescribed notice of intended publication is given. (2) To avoid doubt, if —(a) the first publication of the new work only includes part of the old work; and (b) a later publication of the new work includes any other part of the old work that was not included in any earlier publication, then — (c) subsection (1) does not apply to the later publication just because it applies to the first publication; and (d) the later publication is to be treated as the first publication of the new work for the purposes of applying subsection (1). (3) Where an authorial work, being unpublished old material in a public collection, is published in circumstances to which subsection (1) applies, the publication is deemed to be authorised.
