What are repositories and why are they useful?
02/09/2021

An open access repository is a digital repository where the content is freely available to download and reuse (sometimes with restrictions), where no login or subscription is required.
An institutional research repository is a digital repository for the storage of outputs from research undertaken at an organisation. They can be wholly open access repositories, closed access, or a mixture. Content that you might expect to find in an institutional research repository are: research papers, working papers, reports, datasets, and other digital objects resulting from research.
Collectively they store, preserve and provide access to a vast wealth of the world’s research output, and are free for us to use!
