All Nigerian Publishers that have obtained ISBN and are intending to publish in Nigeria can apply for CIP data.

All monographs (i.e. books) published in Nigeria which bear a Nigerian town/city as a place of publication and are likely to be acquired by Libraries are eligible for CIP.

Ø Obtain ISBN;
Ø Submit copies of preliminary pages of your forthcoming titles;
Ø Obtain CIP data sheet and fill them;
Ø Submit CIP data sheet to the CIP unit for processing.

There is no relationship between the CIP Programme and Copyright registration.
The main objective of CIPS is to describe the bibliographic characteristics of a work and thereby facilitate access to it in library catalogue.

There is no charge for CIP processing. However, participating publishers are obligated to send three, ten and twenty five copies of private, State government and Federal government publications respectively to our Legal deposit office.

Cataloguing-In-Publication (CIP) data is available only for works that are not yet published.

Most CIP data are completed within ten (10) working days (two weeks) of the receipt of these materials in the CIP office, a copy of the data will be returned to you for printing in the book, usually on the verso of the title-page.

Most CIP data are completed within ten (10) working days (two weeks) of the receipt of these materials in the CIP office, a copy of the data will be returned to you for printing in the book, usually on the verso of the title-page.

The first city/town mentioned will determine which National CIP programme should supply the CIP data for example, if Abuja, Abidjan, Accra and Lome are used in the imprint with the name of only one Publisher, the National Library of Nigeria will be responsible, since Abuja is mentioned first.

Two sets of CIP data - may be obtained. In case of Longman, Macmillan, UPL etc., the National Library of Nigeria will supply one set and the British Library a second and it is left to the Publisher to decide which one he should print in the book. There is no need to print the two sets of data in the same book.

The CIP data should be printed without alteration on the verso page i.e. the reverse page of the title page and with the heading: National Library of Nigeria CIP data.
