Observatory of open access

This observatory aims to monitor the state of Open Access in Catalan universities. Currently, the source of information used is Openalex.

Following the initiatives of other countries such as Denmark, Netherlands and the United Kingdom, this observatory shows the results of the participating institutions obtained from it methodology for remote services. It also presents the aggregated information.

The results complement the data shown by the open access publication indicator of the Research Portal of Catalonia (PRC). This indicator presents the total number of publications and theses that are in the PRC in open and closed access and the average open access publications. More information about the PRC indicator.

The Observatory is also complemented by the Open Access thermometers of the Universitat de Barcelona, Universitat Autònoma de Barcelona, Universitat Politècnica de Catalunya I la Universitat Pompeu Fabra.  

Soon, the Observatory will present the costs of researchers and institutions when publishing openly.


The Observatory shows for each year since 2011, the scientific articles of each university published in open and closed access.

Until 2021, the degree of openness has been calculated from data extracted from Web of Science and Scopus and using the Unpaywall. The dataset with the data 2011-2021 is published in CORA-RDR. 

From 2023, data extracted fromOpenalex from ROR of each university. 

After removing the duplicates, the DOI retrieves the number of items that:

  • They have been published in purely open access magazinesPolenta
  • have been published in hybrid journals, ie subscription journals that offer authors to publish in open access immediately by paying a Article Processing Chargehybrid
  • They have free access but the articles have no license: bronze Bronze
  • They are only open in institutional or thematic repositories Repositories
  • they are not in open access No open access 

When an item is in a repository but is not in open access because it has an embargo it is not counted as open access.

When an article is published openly in a journal and in a repository it is counted only once, prioritizing publication in the journal and not deposit in the repository (Charts 1 and 2).

Instead, Graph 3 shows a column for each participating university and shows the availability of copies in repositories of the pure, hybrid, and bronze options.

The information is updated 2 times a year, during the months of April and October.
