The cataloguing-in-Source given up by the LC in 1959 was revived in July 1971. The entries were prepared from galley proofs and data returned to publishers within ten working days. Subtitle, imprint and collation were not given. However, the LC includes this information later in the MARC. The MARC is made available four to six months before the book's publication.
There are three products of Cataloguing-in-Publication (CIP). Namely;
(1)Record of CIP cataloguing data on MARC tape made available before the final cataloguing copy appeared on the MARC tape.
(2) The LC cards made available before the publication date of the book.
(3) Cataloguing data printed in the book itself. You might have seen that some American and British Books carry the Cataloguing-in-Publication information in the back of their title pages.
