Maintenance Culture in Academic Libraries of Universities in South West, Nigeria (Published)

This study explored maintenance culture in academic libraries of universities in south west, Nigeria by taking a cursory look at Lagos State University Library, Ekiti State University Library, Ado – Ekiti and Olusegun Oke Library of Ladoke Akintola University of Technology, Ogbomoso as case studies. Related literatures were reviewed on sub heading that concerns the subject matter. Descriptive survey research design was adopted for the study. Fifty (50) questionnaires were distributed to each of the university library sampled for the study making a total of One Hundred and Fifty questionnaires (150) in all. Out of this One – Hundred and Twenty Eight (128) were returned valid. Four point Lickert scale was used to elicit responses and data collected analysed using frequency count and percentages (%). The findings of the research work indicated some causes of deterioration of library materials in south west Nigeria which are characterized by high temperature and humidity, natural ageing, mutilation by users, insect activities among others. Some of the maintenance practices identified in the course of the work as being practiced were careful removal of documents from shelves, binding of torn books, fumigation, photocopying, digitization, mounting of securities to check delinquencies among others. It was revealed that there were lack of constant training and retraining for staff on preservation, no preservation policies, inadequate funding, lack of functional library equipments for preservation and conservation among others. Based on the findings, the study recommended the following: working policies should be formulated on maintenance, training should be organized, open communication should be established between library management and university community, equipment on preservation and conservation of library materials should be procured.

Material Compatibility in Conservation of Traditional Earth Building in Nigeria Case of Origbo Communities in Osun State in South-West of Nigeria (Published)

This paper analysed intervention strategies for the conservation of traditional earthen architecture which are selected in response to ageing earth building walls, being exposed to agents of degradation, some superficial deterioration were observed pointing to necessity of applying a compatible conservation to specific deterioration defects of earth building. There are various methodological approaches to conservation, it is therefore essential to understand material compatibility for implementing proper intervention. The study examined the major origin of defects on earth building due to wrong material composition used in conservation especially the damaging effects of cements on earth building. The paper presented conservation structure as related to appropriate material composition and compatibility. Also, properties of earth were examined that enables compatibility in conservation, this include permeability, plasticity, density, thermal conductivity, capillary absorption and drying shrinkage. The paper then concludes with essential factors of material compatibility to effective earth building conservation.

Conservation of Traditional Earth Building in Nigeria: Case Study of Origbo in Ife North, Osun State (Published)

Increasing awareness of the past, present and continuous use of the earth as a building material draws attention towards main concept of conservation of the traditional architectural heritage at the rural communities of Origbo in Ife North Local Government of Osun State. The aim was to find out the main problem regarding earth building deterioration with emphasis on the distinguishing character of natural deterioration process of earthen architecture. The study revealed further that moisture attack is the major medium through which earth building deteriorate, also lack of maintenance, bad construction techniques, leaking roof, inappropriate roof eaves over-hang and lack of drainage for rain water are the medium of deterioration. This paper presented conservation model approach to earth buildings that are compatible with characteristics of earthen building materials. The paper then concludes with fundamental strategies that could help to conserve traditional earth building and to improve the durability of earth dwellings.
