Croatian Repositores and Archives Aggregator (ARA) collects in one place metadata of Croatian repositories with implemented support for OAI-PMH.
If you are a user looking for information, through ARA you get a web site where you can see the catalogue of Croatian repositories and archives and search, in a centralized way, all their metadata. Through search results you are referred to the papers in original repositories.
If you own a repository, by registering the repository in ARA, you get an additional channel for dissemination of digital content from the repository. By increasing visibility of the content, the likelihood of its utilization and citation is also increased. You can register your repository or archives in ARA online, the registration form and information on the conditions of registration can be found at ARA's website.
Ara is listed in the Registry of OAI.PMH service providers which is maintained by Open Access Initiative (OAI). In addition to the Registry of service providers, the Initiative also maintains a registry of data providers in which our Hrčak has been included for many years.
