National Bibliography in Nigeria: Its Growth, Development and International Dimensions
Nigeria was the first country in Black Africa to have a current national bibliography. The responsibility for the production of the national bibliography, known as Nigerian Publications from 1953, when the first issue appeared, to 1973 when it changed its name to the National Bibliography of Nigeria, was transferred from the Ibadan University Library, Nigeria's largest research library, to the National Library of Nigeria in June 1970. Although the National Library was officially opened in 1964, it was not invested with this national bibliographic responsibility until 1970. The compilation of the national bibliography by the Ibadan University Library from 1953 to 1970 was a voluntary task not backed up by any national legislation, although the enactment of the Nigeria Publications Ordinance 1950, which required two copies of every book published in the country to be deposited with the Ibadan University College Library, as it was then known, enabled the Library to assume responsibility for the preparation of the national bibliography.
Bibliographic control in Nigeria
AbstractIn summary, Nigeria has a well established national bibliography following international standards. What is needed now is a refinement in the collection policies, in the cataloguing of Nigerian language material, and in the subject analysis of Nigeriana. These problems might be solved by (a) efficient decentralization of the collecting and cataloguing activities as is done in Canada, and (b) by agreed national policies on modifications of LC classification and subject headings. Planning for the conversion of the national bibliography to machine-readable form will proceed apace.Access to national collections by way of union lists is in need of central co-ordination to eliminate duplication of effort and to enable utilization of already existing machine-readable files. This co-ordination is a responsibility of the National Library, being the national bibliographical centre, but the planning and implementation can be shared with other libraries in the country.
Evaluation of antioxidants by a rapid polarographic method
A simple, rapid, precise, and reproducible method and an adaptable apparatus for polarographic measurement of lipid peroxidation and antioxidant activity is described. This method measures antioxidant activity within a few min time as compared to the hours or days needed for several widely used methods. Peroxidation rates were measured for different lipids as a function of amount of lipid, and amount of biocatalyst. The method is applicable to the detection and measurement of the antioxidant effects exhibited by weak antioxidants and has been satisfactorily used for the measurement of the antioxidant activity of different concentrations of powerful antioxidants.
