Repositories are collections of scholarly material and all into two main categories:
- Institutional repositories: archives for collecting, preserving, and disseminating digital copies of the intellectual output of an institution, particularly a research institution
- Themed repositories: repositories for collecting subject -specific or type-specific scholarly output.
Repositories are very good for providing access to scholarly material that otherwise might require payment to access. Repositories are good in general, but just make sure you know what you are reading: a piece of scholarly research published in a respected journal, or a student assignment that got 60% or above - you'll find both in institutional repositories. That isn't meant to be disparaging to student essays and assignments, but to simply remind users that institutional repositories may contain both kinds and it's more likely that users are looking for published scholarly research. Repositories are great for showcasing student work - which is great for the writer's CV and shows other students examples of both what an essay or assignment looks like and what is required to get a good mark. It's also worth mentioning that there are good quality peer-reviewed journals that are dedicated to publishing student work.
