The purpose of this paper is to show the quality control process and techniques of an open-source digital library (DL)/institutional repository (IR) in an institution. It will also demonstrate the challenges for quality control of a digital library in an institution.

It will explain metadata quality control and structural quality control and some matters that are important for an ideal IR. It also describes data migration from one repository to another.

Metadata without quality is just junk. Library personnel should have adequate library science educational qualifications to do the DL work. Non-professionals may create junk in the IR. Quality control can ensure the standard of a digital IR.
