Metrics regarding Open Access (OA) availability for readers and the enablers of redistribution of content published in scholarly journals, i.e. content licenses, copyright ownership, and publisher-stipulated self-archiving permissions are still scarce.
This study implements the four core variables (reader rights, reuse rights, copyrights, author posting rights) of the recently published Open Access Spectrum (OAS) to measure the level of openness in all 1728 Spanish scholarly journals listed in the Spanish national DULCINEA database at the end of 2015.
In order to conduct the analysis additional data has been aggregated from other bibliographic databases and through manual data collection (such data includes the journal research area, type of publisher, type of access, self-archiving and reuse policy, and potential type of Creative Commons (CC) licence used).
79% of journals allowed self-archiving in some form, 13.5% did not specify any copyright terms and 37% used CC licenses. From the total journals (1728), 1285 (74.5%) received the maximum score of 20 in reader rights. For 72% of journals, authors retain or publishers grant broad rights which include author reuse and authorisation rights (for others to re-use).
The OAS-compliant results of this study enable comparative studies to be conducted on other large populations of journals.
