Amid continuing global challenges due to the pandemic, 2021 was another noteworthy year not only for COS, but for the broader research community. The theme, “Accelerating Open Science” is based on our observations of an accelerating shift toward openness-as-default. This shift is being driven by the collective, collaborative actions of researchers and stakeholders committed to providing research progress. The full Impact Report highlights our achievements, our relationships, and our community support, and we hope you’ll take the time to review it. Thank you for your individual and collective actions to change the default to open so that the scientific ideals are manifest and rewarded in everyday practice.
