This document discusses open access resources and the open access movement. It begins by explaining that most research is publicly funded but published in expensive journals, making the results inaccessible to most. The open access movement aims to make all research findings available to society. It describes various definitions and initiatives to promote open access, such as allowing authors to self-archive works in institutional repositories and publish in open access journals. Examples are given of important open access resources and publishers like DOAJ, DOAB, PLOS, and BioMed Central. The conclusion states that open access maximizes the visibility and impact of research.
