According to Hawkins (2021) maintaining and taking care of rare, fragile and endangered materials and artefacts by means of digitization using digital
technology, computer devices, cell phones, digital cameras, recorders, and digital displays to ensure perpetual access is regarded as digital preservation.
Digital preservation efforts are carried out with an item that is at risk of being lost or destroyed due to bit deterioration, degenerate activities, being outdated, and so on. However, there is no guarantee that all artefacts will be preserved and well-maintained in digital preservation (Lee, Slattery, Lu, McCrary, 2019).
However, certain techniques are used to ensure the preservation of the digital object. Three basic techniques are used to maintain the dignity of digital objects while still allowing users to retrieve, view, and use them in the face of constantly evolving technology. There are three fundamental techniques use in preserving digital document which includes migration, emulation refreshing.
Refreshing: entails transferring a file from one physical storage medium to another regularly to prevent obsolescence or deterioration of the storage medium. Since digital storage devices deteriorate and technological advances render older storage devices obsolete to new computers, ongoing refreshing is likely to be needed for several years to come. For example, as part preservation strategy, it is recommended that copies of electronic files maintain on other devices, such as external hard drives, and cloud technologies. The external hard drives should be reviewed regularly to ensure that it is still operational. When the drive is several years old, the data stored on it can be refreshed by transferring it to a new hard drive.
Migration: Data migration is the method of transferring data from one hardware or software configuration to another, or from one generation of computer technology to the next while preserving the data's unique characteristics. The number of common file formats available will gradually be reduced as a result of migration. It has been shown that any data migration, when performed correctly, helps to create more transparent standards, simplified workflows, and best practices. While migration can be a challenging process, it does not have to be if it is well-planned.
Emulation: In that it focuses on the application software rather than the data files, emulation is similar to migration. Emulation is a technique that uses software and hardware to mimic the essential characteristics of one computer on another, allowing programs written for one environment to run in another. The development of emulators, which are programs that translate code and instructions from one computer to another, is needed for emulation. Emulation allows for the use of older data on new computers.

4.0 CONCLUSION
In this unit, you learnt the definition of Institutional Digital Repository (IDR) as an online archive for collecting, preserving, and disseminating digital copies of the intellectual output of an institution, particularly a research institution.
Additionally, various digital repository softwares were highlighted, these include; Dspace, Green Stone, Flexible Extendable Digital Object Repository Architecture (FEDORA) among others. Also, in this unit, benefits of
digitisation were discussed which include; increase the exposure and visibility of an institutional scholarly contents; store, maintain and preserve the intellectual output of an institution, such as unpublished or otherwise easily lost literature (i.e., grey literature), such as theses/dissertations or technical reports, in a single location; showcase and make institutional content more readily accessible to users. Also, you leant the meaning of digital preservation different type of digital preservation strategies and techniques. The three fundamental techniques use in preserving digital document includes migration, emulation refreshing.
5.0 SUMMARY
The summary is provided as follows:
• “An institutional repository is a digital archive of the intellectual products created by faculty, research staff, and students of an institution, with few, if any, barriers to access”.
• The basic goals of providing an institutional repository are as follows:
to increase the exposure and visibility of institutional scholarly contents; to store, maintain and preserve the intellectual output of an institution, such as unpublished or otherwise easily lost literature (i.e., grey literature), such as theses/dissertations or technical reports, in a single location; to showcase and make institutional content more readily accessible to users, to facilitate scholarly communication.
• Open-source digital library softwares that have been deployed and tested on a wide scale include; Green stone, Dspace, Fedora, and E-print among others 6.0 SELF-ASSESSMENT
