Information for referees / librarians

The Liblink initiative of the Ibero-American Consortium for Education in Science and Technology (ISTEC) has among its central objectives the free sharing of bibliographic collections found in the libraries of the institutions associated with the consortium.

To start working on the LibLink initiative, each new member must provide their institution’s data in the format detailed below in order to be published on the ISTEC website and in the Celsius directory.

Send this data to: Virtual Office of Institutional Relations ISTEC

Access to the different library sites that share their collections

Participating institutions have libraries that display their catalogs on the Internet. When an institution wishes to make a request, it must search the catalogs of the other institutions, locate the bibliographic material and, subsequently, request it from the institution that owns it.


Access to the Request Management Software

For the management of bibliographic requests within the LibLink initiative, Celsius software is used, provided free of charge to ISTEC members participating in the initiative.

This software allows the institution to administer, register and control the information of the bibliographic exchange carried out by its libraries and users, as well as by users external to that institution. The official Celsius site is located at, and its development and maintenance is carried out by the Library Link Project (PREBI) of the National University of La Silver.

To access the detailed information of the institutions that are part of Liblink you must access: “The updated list of institutions, contacts and catalogs can be accessed by clicking here.”, Where you can see the different catalogs of the different libraries to search bibliography, contacts and addresses of the Celsius sites where to place orders.

To obtain a new instance of Celsius, each institution must:

  • Create a DNS record CNAME celsius.domain-of-the-institution (eg,,, etc.) that points to You can use another subdomain (eg liblink.domain, exchange.domain, service.domain, etc.) if you find it convenient for your institution and / or its users.
  • Send an email to with the following information:
    • CNAME domain created.
    • Name, surname and email of one of the people in charge of the administration of the exchange service in the institution. This person can then register other administrators.
    • Optionally, they can also send:
      • Email address of the exchange service (if not provided, the administrator’s will be used).
      • A logo 100 px high by 200 px wide, in jpg or png format and preferably with transparent background, to place in the header.
      • Title and subtitle to show in the header (see image below).
      • Text with description of the service for its users (it will appear on the main page of your instance).

  • Ordering at Celsius

By making a request for bibliographic material, it should be taken into account which version of Celsius the target library uses. When material is requested from another institution that operates with Celsius NT or earlier versions, the person responsible for the exchange must request a login and password at the destination institution. For this you must register on the Celsius site of the corresponding institution. In the case of said institution operating with Celsius 3, the request can be transmitted from the Celsius instance of the requesting institution. Due to copyright protection laws, the exchange of documents can only have problems between libraries, therefore the user must belong to the library staff of the ISTEC member institution and be in charge of placing orders to the different member institutions.

In the case of institutions with Celsius NT or earlier, after receiving the access data the librarian can place their orders on the User Site, for this you must enter the option “Add Order” where you can enter the corresponding bibliographic information, according to The type of material (article, book chapter, conference proceedings, etc.) will display a different form.

Orders between institutions are called “provision.” The librarian must enter all the data of the publication and in the cases that correspond the physical location in the library to which the order is placed. Once the order is loaded, you can see its status directly on the Celsius site where it was placed. In this way, the requesting institution finds out when the material is available in the pdf format.


  • Recommendation

Due to the large number of participating institutions, it is advisable to perform a rotation of libraries to which the information is requested, distributing the work over the network.


  • Warning

Please periodically review the documentation on the official sites. We are working to improve the network and making changes.
