Having created and populated your repository, you will want your content to be indexed by the search engines and aggregating services that most people use. A good way to kick this off is to register your repository with the following directories. At the very least they will provide links that indexing robots can follow to your website, but the directories may even be used as an authority file to filter the repositories that are indexed.

DSpace Instances

This is a page in the DSpace wiki, and naturally enough only lists repositories that run DSpace software. To add your DSpace repository, click on the 'Edit tab' against the relevant alphabetical section to edit the page, then copy the format of adjacent entries.

OAIster page

OAIster is a search service for OAI-compliant digital resources, not just open access repositories. It harvests metadata for the content of these resources using OAI-PMH.

OAIster's list of data contributors is used by Google Scholar to control its crawling of open access repositories. Registered Data Providers page

This registry of OAI Base URLs is hosted by the Open Archives Initiative. One advantage of registering is that the functionality of your OAI Base URL is automatically validated.

OpenDOAR – Directory of Open Access Repositories page

OpenDOAR is a quality-controlled worldwide directory of academic open access repositories maintained by SHERPA, University of Nottingham. It has strict criteria for inclusion, the key conditions being that the repository must contain some full-text items, and it must be accessible without the need for a username or password. Each repository is visited by OpenDOAR staff for in-depth indexing purposes, rather than relying on automated analysis. As well as providing a simple repository list, OpenDOAR lets you search for repositories, or search repository contents.

OpenDOAR data is used to control harvesting by Intute Repository Search and other search services.

ROAR – Registry of Open Access Repositories page

This worldwide registry is operated by the University of Southampton. Its strong points include statistics on the growth rates of individual repositories, cumulated globally. These are compiled using OAI-PMH. Associated services include statistics on file formats, and ROARMAP – a database of institutional and funders' Open Access archiving policies.
