Digital archives and digital library projects are being initiated all over the world for materials of different formats and domains. To organize, store, and retrieve digital content, many libraries as well as archiving centers are using either proprietary or open-source software. While it is accepted that print media can survive for centuries with some physical preservation techniques, digital media requires continuous processes to keep it compliant with current technology. It is not only necessary to organize digital content but also important to preserve it to ensure accessibility, sustainability, and retrieval across time. This paper presents an analytical study along with observations regarding digital preservation support available in existing open-source digital library software (OSS-DL) based on test beds created for that purpose.
