Investigating the effectiveness of integrating Controlled Subject Vocabulary Sets in The University of Zambia Institutional Repository

The University of Zambia Institutional Repository (IR) has seen an improvement in the amount of digital objects being deposited therein. However, the system interface seems not to utilize subject-specific controlled vocabulary sets, leading to difficulties on the part of contributors in depositing their materials in the right location. The lack of controlled vocabulary sets also leads to ineffective search and browsing of the IR by other users of the IR. Hence the need to integrate subject controlled vocabulary sets into the UNZA IR cannot be over emphasized.
