The creation of repositories, either subject based or institutional, is one of the answers of the Open access movement on the so called serials crises. Nowadays there are so many initiatives that it is hard to find a good starting point. In this chapter I try to order some of these initiatives.

Overall there are 3 aspects to these consider when dealing with these repositories.

  • Searching collections repositories
  • Collections of repositories
  • Individual repositories


Searching collections of repositories


BASE http://digital.ub.uni-bielefeld.de/index.php

Bielefeld Academic Search Engine is een search engine that uses the OAI protocol to harvest the metadata from nearly 549 repositories. It has currently indexed some 7.5 million articles.


Narcis http://www.narcis.nl

Narcis is a search service which gives free access to academic research output in the Netherlands. This is a broad collection which guarantees digital accessibility to the full text without any restrictions. DAREnet consists of nearly 320.000 OA text objects.


OAISTER http://oaister.worldcat.org/

OAIster is a union catalog of millions of records representing open access resources that was built by harvesting from open access collections worldwide using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Today, OAIster includes more than 25 million records representing digital resources from more than 1,100 contributors.


Scirus http://www.scirus.com/

Discussed before, allows full text searching of selected repositories!


Scientific Commons http://en.scientificcommons.org/

An impressive search engine based on the OAI protocol. It indexes 898 repositories from 51 countries. It has indexed more than 17 million items. The fulltext plus metadata of the articles is being indexed up to a limit of 3 MB. But above all, the search engine is really fast. It really is one of the most interesting search engines.


Collections of Repositories

In the library world there appears a lot of envy, so rather than cooperating we like to start from scratch again, so we end up with at least two collections of OA repositories.


ROAR http://archives.eprints.org/

The first overview of OA repositories.


openDOAR http://www.opendoar.org/

The youngest overview of OA repositories. They have made use of Google Custom Search to search for the full text deposited in all all the listed repositories.


Individual Repositories

Individual repositories can be either subject specific, or institutional. Only a few examples of subject oriented will be provided, since there are too many of them to include in this course. The afformentioned collections of repositories do a better job on listing the individual repositories.


Subject Repositories

ArXiv http://arxiv.org/

The classsical example of a subject specific (physics) repository. It covers about 400,000 e-prints in Physics, Mathematics, Computer Science and Quantitative Biology. The artcles can only be searched on metadata.


Organic Eprints http://www.orgprints.org/

Organic Eprints is an international open access archive for papers related to research in organic agriculture. The archive contains full-text papers in electronic form together with bibliographic information, abstracts and other metadata.


E-lis http://eprints.rclis.org/

E-LIS is an open access archive for scientific or technical documents, published or unpublished, on Librarianship, Information Science and Technology, and related areas. The repository contains some 4700+ items.


DList http://dlist.sir.arizona.edu/

Established in 2002, DLIST, Digital Library of Information Science and Technology is a cross-institutional, subject-based, open access digital archive for the Information Sciences, including Archives and Records Management, Library and Information Science, Information Systems, Museum Informatics, and other critical information infrastructures.


PubMed Central http://www.ncbi.nlm.nih.gov/pmc/

PMC is a free full-text archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health's National Library of Medicine (NIH/NLM). 







Institutional repositories

Only a few examples (since there are hundreds of them)


T-Space https://tspace.library.utoronto.ca/

T-Space showcases and preserves the scholarly work of University of Toronto faculty. T-Space is faculty space, established by the Library to support the dissemination of knowledge by the University community.


Wageningen Yield http://library.wur.nl/way

Wageningen Yield (WaY) is the access point to scientific and other publications originating from Wageningen University and Research Centre (Wageningen UR).
