Information for reference and regular librarians

One of the main goals of the LibLink Initiative by the Ibero-American Science and Technology Education Consortium (ISTEC) is the free sharing of the bibliographic assets of the member libraries of the consortium.

To start working on the LibLink initiative, each new member is required to provide institutional data in the format specified below so that they can be published on the ISTEC website and in the Celsius directory. Submit this data to ISTEC’s Institutional Relations Virtual Office

Access to the different library sites that share their collections

The participating institutions have libraries that display their catalogues on the Internet. When an institution wants to submit a request, it should browse the catalogues of the other institutions, locate the bibliographic material and submit a request for the relevant content to the institution that owns it.

Access to Request Management Software

Celsius is the software used for managing bibliographic requests within the LibLink initiative and it is provided free of charge to ISTEC members who make part of the Initiative. This software allows the institution to process, record and control the information related to the bibliographic exchange carried out both by its libraries and users, as well as by external users. The official website for Celsius is, developed and maintained by Proyecto de Enlace de Bibliotecas, Universidad Nacional de La Plata (PREBI UNLP). To access the detailed information regarding the institutions that are part of LibLink, please visit: “The updated list of institutions, contacts and catalogues can be accessed here“, where you can see the different library catalogues to search bibliography, contacts and addresses of the Celsius sites available to submit your requests.

Each institution that joins LibLink needs a Celsius instance to manage its requests, communicate with its users and obtain its own metrics and statistics on the service. The installation, maintenance and update of instances is also done by PREBI UNLP; therefore, institutions do not have to assign additional resources for these tasks.

To obtain a new instance of Celsius, each institution is required to:

  • Create a DNS CNAME register, celsius.institutions-domain (e.g.,,,, etc.) that points to You can use another subdomain (e.g., liblink.domain, exchange.domain, service.domain, etc.) if you consider it more convenient for your institution and/or its users.
  • Please, send an e-mail to, with the following information:
    • CNAME domain created
    • Name, surname and e-mail of the person responsible for managing the exchange service in the institution (Exchange Officer). This person can then register other administrators
    • Optionally, they can also submit:
      • E-mail address of the exchange service (if not provided, the administrator’s address will be used)
      • A 200 px (width) x 100 px (height) logo, in jpg or png format and preferably with transparent background, to be placed in the header
      • Title and subtitle to be displayed in the header (see image below)
      • Text with description of the service for the users (it will appear on the main page of your instance)
      • Configuration of the smtp server (user, password, host and port)

Submitting a request in Celsius

The request for bibliographic material depends on the version of Celsius used by the target library. To request material from another institution that operates with Celsius NT or previous versions, the exchange officer needs to request a login and password to the destination institution. For this, the officer needs to register in the Celsius site of the relevant institution. If the institution operates with Celsius 3, the request can be processed from the Celsius instance of the requesting institution. Due to copyright protection laws, the exchange of documents can only be done between libraries, therefore the user must belong to the library staff of the ISTEC member institution and be in charge of submitting the requests to the different member institutions.

Institutions using Celsius NT or previous versions, can submit their requests on the User’s Site after receiving the access data for the librarian; go to the option “Add Request” where you can enter the corresponding bibliographic information, and based on the type of material (article, chapter of book, conference record, etc) a different form will be displayed. Requests between institutions are known as “provision” requests. The librarian needs to enter all the publication data and if required, the physical location of the library to which the request is submitted. Once the request is loaded, you can see its status directly on the Celsius site where the request originated. Thus, the requesting institution is notified when the material is available in pdf format.


Due to the large number of participating institutions, it is advisable to rotate the libraries to which the information is requested, so as to evenly distribute the work in the network.


Please regularly review the documents posted on the official sites. We are working to improve the network and making changes.
