Open access increases and improves the transparency of the scientific process and access to knowledge, favouring the dissemination of science among citizens and giving society the capacity to face the complexities of the 21st century.

Scientific institutions and authors immediately increase the visibility of their research results. The dissemination and use of the research is increased, achieving a greater impact and opening up the way to new opportunities and funding.
Researchers save time searching for resources that they are unable to access through their institutions unless they have subscriptions to journals. .
It allows research funding entities, universities and research centres to monitor the quality and transparency of the research process and the return on investment in research.
Libraries can offer their users access to more academic materials, optimizing budget investment and allowing an adequate part of it to be dedicated to technological infrastructures. This gives them the possibility of assuming new roles as providers of open access services and as advisers of new forms of scientific and academic communication.
Publishers who adopt open access gain greater visibility for their publications. Their business models become more transparent, they are more open to new opportunities and they are able to focus on providing new value-added services for the community.
Companies benefit from immediate open access to pioneering research results that allow them to innovate by developing and introducing new products and services that increase their competitiveness. Limited access to academic production through subscriptions is an obstacle to business innovation, especially in the case of SMEs.
