Institutional Repositories

Institutional repositories—An increasing number of academic and research institutions are relying on repositories to showcase their research.  This sections offers several guides and directories to repositories.  In addition, several prominent repositories are singled out.

  • OpenDOAR – The Directory of Opean Access Repositories
    This is an international and comprehensive listing of repositories. By November 2008, it included 1,200 entries. According to its editorial policy, each repository has been visited and its value verified. This directory has, in addition to an alphabetical list, an index by major continental areas and countries within each of them. It also has a search engine for searching and browsing repositories by several parameters: subject area, content type, repository type, country, language, and software. A summary attached to each repository includes: name, organization, description, software, size, subjects, content, language, and policies. The section of Statistical Charts provides a graphical description by several criteria such as: types, subject, languages, etc. Housed at the University of Nottingham, UK, OpenDOAR is recognized as an authoritative source and it is supported by the Open Society Institute (OSI), along with the Joint Information Systems Committee (JISC), the Consortium of Research Libraries (CURL) and SPARCEurope.
  • Ranking Web of World Repositories
    This is an initiative of the Cybermetrics Lab, a research group of the Consejo Superior de Investigaciones Científicas (CSIC), Ministry of Education, Spain. The ranking is based on four criteria: size, visibility, rich files, and scholarly content (see the Methodology section). The repositories selected are based on the listings provided by the Registry of Open Access Repositories (ROAR), and The Directory of Open Access Repositories (OpenDOAR). In addition to the list of the Top 300, the directory also has an alphabetical list of nearly 600 entries that complied with their selection criteria. The Glossary provides information about the meanings of terms used in the building of the ranking. It also has a section on Best Practices for repositories. 
  • Repository 66
    This is graphical interface using Google Maps that shows the location of institutional repositories around the world. It is based on the listings of repositories provided by the Registry of Open Access Repositories (ROAR), and The Directory of Open Access Repositories (OpenDOAR). Repository 66 uses an eight-color circle code to show the software used (Dspace,  EPrints, BePress, etc.). By clicking on a circle, the reader finds information about the repository, URL, the OpenDOAR description, growth, and searching capabilities. You can limit your map to, for example, the type of platform and country.
  • Charles W. Bailey, Jr., Instiutional Repositories, Tout de Suite
    As quoted from the introduction of this document: "Institutional Repositories, Tout de Suite is designed to give the reader a very quick introduction to key aspects of institutional repositories and to foster further exploration of this topic though liberal use of relevant references to online
    documents and links to pertinent websites". Some of the topics included in this 'instant' IR summary are: What is an institutional repository? Why should my institution have an IR? What is self-archiving? Can authors legally deposit articles in IRs? What software is used for institutional repositories?  This document is part of Digital Scholarship, a website dedicated to scholarly electronic publishing and open access.

Examples of repositories:

  • Cornell/
    arXiv (archive) is a pre-publication repository of selected areas in the fields of physics, mathematics, non-linear science, computer science, quantitative biology and statistics.  It contains over a half-million openly-accessible articles with a predicted growth of one million by 2015. Considered to be the largest repository of scholarly articles in the world, it is the product of a culture of extensive document sharing very common throughout the physics community. arXiv is partially funded by the National Science Foundation, and operated by Cornell University. arXiv is powered by various software.
  • MIT/Dspace
    Compromised by fifty-eight communities representing many of MIT's departments and research centers, Dspace's main objective is to archive and share the university's digital research materials produced by faculty and research staff. It is designed to store articles, datasets, images, course materials, and other digital objects for quick distribution and worldwide visibility. It includes a collection of over twenty-thousand MIT theses. The MIT OpenCourse Ware - MIT OCW Archived Courses is a one of the most interesting collections of this repository.
  • University of Michigan/
    Deep Blue

    Deep Blue is intended to serve as an archive for the preservation and dissemination of the best scholarly and artistic work done at the University of Michigan. There are over 75 collections representing most of the academic departments and research units of the university. At present 50,351 authors have contributed to 44,580 scholarly or artistry electronic objects. This repository is browseable by collections, titles, authors, or by topics. In addition, a search engine can perform more specific searches. Deep Blue is powered by Dspace.
