The purpose of this study was to evaluate the usability effectiveness of a webware for electronic theses and dissertations (ETDs) in Nigerian repositories. The webware (etdsearch.com.ng) is a web application system that curates ETDs from three sampled Federal government-owned universities. The system also links users to the repositories where the theses and dissertations are hosted.

The case study research strategy was adopted for the study. Sixty postgraduate students from three universities were randomly selected. A usability evaluation questionnaire based on the ISO 9241-11 framework was used to collect data after performing pre-defined queries/tasks based on the informational and transactional query models. The research questions were analysed using the median of the performance score (f_x) of the three universities for each item evaluated, while the Kruskall–Wallis test by ranks was used to test the null hypothesis at a 5% level of significance.

The study answered two research questions and tested two null hypotheses on the usability effectiveness of the webware based on the informational and transactional queries. The participants found the ETD search system effectively useable. In addition, there was no significant difference in the opinions of the participants.

The webware used simulated repositories as a feed bed for the ETDs in order to have control over the workability of the repositories. Thus, the results may differ slightly when “live” repositories are used.

The effectiveness of a webware that aggregates ETDs in Nigerian repositories will present libraries in Nigeria with evidence on how these systems work and can be improved upon.

There is a dearth of literature on practical usability studies of digital information systems in Nigerian libraries.

The purpose of this study is to investigate the performance of electronic theses and dissertations (ETD) initiatives in the repositories of federal government-owned universities due to the poor global visibility of ETDs from Nigeria.

An explanatory case study empirical research method was adopted for the study. Using an adapted methodology of Ghosh (2009) and multiple data gathering techniques, data was collected based on the three domains of the network of excellence on digital libraries (DELOS) digital library reference model.

The ETD initiatives in repositories of Nigerian federal universities have not made remarkable progress as digital libraries based on policy, content and system architecture. The specificity of ETDs is not clearly stated in the policies where available. The repositories housing the ETDs are also not compliant with the open archive initiative-protocol for metadata harvesting framework.

The study focussed on ETD initiatives in federal government-owned universities. Although the findings of the study are relevant to other institutions in Nigeria and sub-Saharan Africa. It cannot be used as a basis for the generalisation based on other performance metrics.

This research study concluded that electronic theses and dissertations in Nigerian institutional repositories are not well managed for effective service delivery and long-term accessibility. The ill-management of the ETD initiatives is the reason for the poor global visibility and accessibility of these research output from this part of Africa.

The study assessed ETD initiatives using constructs from a theoretical framework.

This viewpoint paper aims to propose a digital and research literacy support program for postgraduate schools in sub-Saharan Africa institutions.

The paper reviewed literature on postgraduate students’ skills and postgraduate information literacy programs and proposed one for postgraduate schools in sub-Saharan Africa institutions.

Information literacy programs are not implemented at the postgraduate level in sub-Saharan Africa possibly because of lack of contents for these programs.

The course is only a proposed course that can be embedded into the postgraduate curriculum in sub-Saharan African universities. The effectiveness of the course has not been evaluated in this study.

The proposed information literacy program focused on digital and research literacy, which is still relatively new in sub-Saharan Africa.
