(26 Oct 2022) AAAS collected 422 responses from U.S. researchers between March and September 2022 to better understand how open access publishing trends and costs are affecting the scientific enterprise and received survey responses from librarians and administrators representing 89 institutions. According to the survey findings, 63 percent of researchers had paid an APC at some point in their career. Among those who had previously paid APCs and answered survey questions about experiences paying APCs, 52 percent of respondents reported that it was difficult or very difficult to obtain those funds, and 69 percent of respondents had used grant funds to cover APC costs.
