This study examined the sustainability of Library Open Source Software (with particular
reference to KOHA) in Nigerian academic and research Libraries. Descriptive survey design
was adopted with a total number of thirty five (35) libraries which were selected purposefully all
over the six (6) geopolitical zones of Nigeria (twenty universities, both privates and publics, ten
Polytechnics, and five colleges of education). Structure Questionnaire was used to generate data
and this was analyzed using simple frequency and percentage. It was revealed that koha is
gaining ground in Nigeria because of its reliability and community involvement. It also revealed
that lack of institutional support; inadequate information and negative attitudes of librarians
were some of the challenges facing adoption and utilization of koha in Nigeria. The study
however made some recommendation.
