A global review of LibLink initiative projects:


ISTEC Metasearch engine

ISTEC metasearch engine unifies searches in members libraries’ catalogues and public collections of Open Access resources. It is a free service, aimed to facilitate access to information on documentary resources by simultaneous and distributed searches on on-line catalogues.



Celsius® software is a tool developed by the PREBISEDICI team at the Universidad Nacional de La Plata that allows to manage bibliographic exchanges as part of the reference services offered by ISTEC institutions. It has been adopted by the consortium as the standard platform for the LibLink initiative and is currently deployed in institutions from 11 countries in the Americas. Celsius software is used by institutions for:

  • Data registration by local users
  • Normalization of requests by operators
  • Registration of the changes in the workflow of the request
  • Monitoring the evolution of an on-line request
  • Delivery of the requested material
  • Access of live statistics with indicators regarding the exchange service.

After the release of Celsius 3.0, this network has switched from a distributed network to a centralized and shared infrastructure. This new architecture is allowing a much faster and easier creation of Celsius instances, permits a more efficient resource management and ensures that all existing instances will always be kept up-to-date. Standard software services are also provided by PREBI-SEDICI’s team, such as server updates, monitoring, automatic backups and support for institutional administrators.

The goal of OPAC is to foster the dissemination of scientific and academic production of the members of the consortium. To achieve this, Open Access resources from ISTEC members are harvested through a the OAI PMH protocol, indexed and exposed via a public search portal. This tool is capable of parsing different cataloguing formats, from which relevant information is extracted, normalized, stored, indexed and aggregated in a central storage database. This database contains hundreds of thousands of academic and scientific resources, including journal articles, undergraduate and postgraduate theses, books and many other types of documents, all of them available under Open Access policies.
